How to calculate average speed
This calculator finds average speed by dividing distance traveled by the time it took — the fundamental physics relationship between distance, time, and speed.
How the calculation works
Average speed = Distance ÷ Time.
Example
100 meters covered in 20 seconds: Average speed = 100 ÷ 20 = 5 m/s.

Pro Tips for Average Speed
- This gives the average over the whole distance/time — actual instantaneous speed may have varied throughout the trip if the pace wasn't constant.
- Keep distance and time in units that produce the speed unit you want (e.g., meters and seconds for m/s, or miles and hours for mph).
Common Average Speed Mistakes to Avoid
- Mixing distance and time units inconsistently (like miles with seconds) without converting, which produces a speed in an unintended, confusing unit.
