Enter the travel distance and your average speed to calculate the estimated journey time, add planned stops, and work out your arrival time.
Planning a road trip and wondering how long it will take to get there? Enter the travel distance and your average speed to calculate the estimated journey time.
For example, if you need to travel 300 km at an average speed of 75 km/h:
So the estimated driving time is 4 hours.
Use the Trip Time Calculator to work out travel duration in hours and minutes instead of calculating it manually.
How Long Will My Trip Take?
The easiest way to estimate trip time is to use:
Example: 240 km at 80 km/h
So the basic trip time is 3 hours.
However, your actual door-to-door journey may take longer because of traffic, fuel stops, meals, rest breaks, tolls, road conditions, or other delays. A travel-time estimate based only on distance and average speed should therefore be treated as an estimate rather than an exact arrival prediction.
How to Use the Trip Time Calculator
You can calculate a trip in just a few steps.
Planning a longer journey? Calculate the basic driving time first, then allow extra time for stops and delays.

Trip Time Formula
The main formula is:
The three related formulas are:
For travel planning, the third formula is usually the one you need.
Example: 450 km at 90 km/h
You are traveling 450 km at an average speed of 90 km/h.
Your estimated moving time is 5 hours. If you plan a 45-minute stop:
The calculation assumes the speed entered represents a meaningful average for the journey.
Calculate Trip Time in Hours and Minutes
Travel-time calculations often produce decimal hours.
Example: 250 km at 60 km/h
That doesn’t mean 4 hours 16.67 minutes. Convert the decimal portion into minutes:
So the result is approximately 4 hours 10 minutes.
This conversion is important when you’re planning an actual departure or arrival time.

Trip Time Calculator With Distance and Speed
If you know your distance and expected average speed, you can calculate the journey duration immediately.
| Distance | Average Speed | Estimated Trip Time |
|---|---|---|
| 100 km | 50 km/h | 2 hours |
| 150 km | 60 km/h | 2 hours 30 minutes |
| 200 km | 80 km/h | 2 hours 30 minutes |
| 300 km | 75 km/h | 4 hours |
| 400 km | 80 km/h | 5 hours |
| 500 km | 100 km/h | 5 hours |
These are moving-time estimates. Actual trip duration can be longer when you include stops and changing road conditions.
How to Calculate Driving Time
For a driving-time estimate, start with the total road distance and a realistic average speed.
Example: 360 km at 90 km/h
If you expect:
This is often more useful for road-trip planning than relying on pure driving time alone.
How Long Does a 100 km Trip Take?
It depends on your average speed.
So distance alone isn’t enough to determine travel duration. You need an estimated average speed as well.
How Long Does a 500 km Trip Take?
Again, the answer depends on your average speed.
At 80 km/h
That’s 6 hours 15 minutes.
If you’re planning an actual trip, remember to add reasonable time for stops and delays.
Calculate Arrival Time From Travel Duration
If you know when you’re leaving, you can add the estimated journey duration to your departure time.
Example: Leaving at 8:00 AM
If you add a 30-minute stop:
Estimated arrival: 12:30 PM.
This is particularly useful when you’re trying to decide what time to leave for an appointment, meeting, airport, event, or destination.

Trip Time With Stops
A common mistake is calculating only the moving time and assuming that is the total trip duration.
Example: 300 km at 75 km/h
Now suppose you plan 30 minutes for lunch, 20 minutes for fuel, and 10 minutes for rest:
If you leave at 8:00 AM, your estimated arrival would be around 1:00 PM, assuming the planned stops happen as expected.
Some calculators distinguish between moving time and total trip time for exactly this reason.

What Average Speed Should I Use?
Use the speed you realistically expect to maintain over the journey, not necessarily the vehicle’s maximum speed.
For example, a road may have a speed limit of 100 km/h, but your actual average might be lower because of:
Using an unrealistically high speed can make your estimated arrival time too optimistic. Your average travel speed should represent the overall journey rather than a short period when you are traveling at your fastest.
Trip Time Calculator in Miles or Kilometers
You can calculate travel duration using either miles or kilometers as long as the distance and speed use matching units.
Using Kilometers
Using Miles
Don’t mix 300 km ÷ 60 mph without converting one of the units first. The distance and speed must correspond to the same measurement system for the direct division to produce hours.
Trip Time Between Two Cities
If you’re estimating trip time between two cities, first determine the actual travel distance by your planned route. Then calculate:
Example: 360 km at 80 km/h
That’s 4 hours 30 minutes. You can then add your planned stops to estimate the total time you should allow for the journey.
For city-to-city travel, don’t use straight-line distance unless you specifically want an air-distance or geometric estimate. Road travel follows the available route, so the actual distance can be considerably different.

Trip Time for Road Trips
For road trips, calculating the basic travel duration is only the first step. A better estimate is:
Example: 600 km at 80 km/h
That’s 7 hours 30 minutes. If you plan 1 hour 15 minutes of breaks:
Your estimated trip duration is 8 hours 45 minutes.
This gives you a much more practical number for deciding when to leave and when you may arrive.
Tracking meal and rest breaks in your hours?
Trip Time for Walking, Running, or Cycling
The same distance-and-speed relationship works for different types of travel.
Walking: 6 km at 5 km/h
Estimated time: 1 hour 12 minutes.
Cycling: 30 km at 20 km/h
That’s 1 hour 30 minutes.
The important part is choosing an appropriate average speed for the activity.
What If My Speed Changes During the Trip?
Don’t simply average two speeds unless the circumstances make that mathematically appropriate.
Example: Two Different Speeds
Suppose you travel 100 km at 50 km/h and then 100 km at 100 km/h.
Simply averaging 50 and 100 to get 75 km/h would give the wrong overall average in this situation because you didn’t spend equal amounts of time at those speeds.
For multi-speed journeys, calculating each section separately is the safer approach.

Common Trip Time Calculation Mistakes
1. Using Maximum Speed Instead of Average Speed
A vehicle might be capable of traveling at 120 km/h, but that doesn’t mean its average speed over an entire trip will be 120 km/h.
2. Mixing Kilometers and Miles
Use km with km/h, or miles with mph, unless you convert the units.
3. Treating Decimal Hours as Clock Minutes
2.5 hours equals 2 hours 30 minutes.
It does not mean 2 hours 50 minutes.
4. Forgetting Stops
Four hours of moving time isn’t necessarily a four-hour road trip.
5. Using Straight-Line Distance for a Road Journey
Road routes rarely follow a perfectly straight line.
6. Adding Stops Twice
If your average speed already represents the whole trip including stops, don’t add those same stops again. Some travel-time calculators explicitly distinguish between moving time and total elapsed time for this reason.
Quick Trip Time Examples
| Distance | Speed | Calculation | Trip Time |
|---|---|---|---|
| 120 km | 60 km/h | 120 ÷ 60 | 2 hours |
| 250 km | 100 km/h | 250 ÷ 100 | 2.5 hours = 2 hours 30 minutes |
| 450 km | 90 km/h | 450 ÷ 90 | 5 hours |
| 600 km | 75 km/h | 600 ÷ 75 | 8 hours |
| 150 miles | 50 mph | 150 ÷ 50 | 3 hours |
These calculations provide the basic travel duration before adding separately planned stops.
Frequently Asked Questions
How do I calculate trip time?
Divide the travel distance by the average speed:
For example, 300 km at 75 km/h takes 4 hours.
How do I calculate trip time from distance and speed?
Enter the distance and average speed into the Trip Time Calculator. The calculation is:
How long will it take to travel 100 miles at 60 mph?
100 ÷ 60 = 1.6667 hours, which is approximately 1 hour 40 minutes.
How long will a 300 km trip take?
It depends on your average speed. At 75 km/h, 300 km takes approximately 4 hours before adding additional stops.
Does trip time include stops?
Not necessarily. Basic trip time calculated from distance and average speed represents moving time. If your calculator has a stop-time input, you can add planned breaks separately.
How do I calculate arrival time?
Calculate the travel duration, add planned stops, and add the resulting total to your departure time. For example:
Can I calculate trip time in kilometers?
Yes. Enter distance in kilometers and speed in kilometers per hour.
Can I calculate trip time in miles?
Yes. Use miles with miles per hour.
What average speed should I use for a road trip?
Use a realistic average for the complete journey rather than your vehicle’s maximum speed. Traffic, junctions, road conditions, and stops can reduce the average substantially.
Can I calculate trip time for walking or cycling?
Yes. Divide the distance by your expected average walking or cycling speed.
What if I travel at different speeds?
For different sections, calculate each section separately and add the resulting times. This is more accurate than simply averaging the speeds.
