Average Speed Calculator (km/h)
Find your average speed instantly. Enter the distance traveled in kilometers and the time taken in hours, and this calculator divides distance by time to give the result in kilometers per hour.
Enter the distance and time to calculate your average speed.
How it works
What is average speed?
Average speed is the total distance traveled divided by the total time taken. It tells you how fast you moved overall, regardless of speeding up or slowing down along the way.
The formula is simple: average speed = distance ÷ time. With distance in kilometers and time in hours, the result comes out in kilometers per hour (km/h).
When to use this calculator
Use it to check your driving pace on a road trip, your running speed during training, or to solve physics homework involving motion. Any time you know a distance and a duration, you can find the average speed.
Frequently asked questions
›How is average speed calculated?
Divide the total distance by the total time. With kilometers and hours, the result is in km/h.
›What if my time is in minutes?
Convert minutes to hours by dividing by 60. For example, 30 minutes equals 0.5 hours.
›Is average speed the same as instantaneous speed?
No. Average speed covers the whole trip, while instantaneous speed is how fast you are going at one moment.
›Can I use miles instead of kilometers?
This calculator uses kilometers. Convert miles to kilometers first (1 mile is about 1.609 km).
›Does this account for stops?
Yes, if you include the stopped time in the total time. Average speed reflects the entire duration of the trip.
