The most basic kinematics formula — average velocity — answered directly from a distance traveled and the time it took.
How it works
Dividing distance by time gives average velocity.
What this does not include
This does not include unit conversion for an already-known speed — for that, use this site’s speed converter instead. This tool derives velocity from distance and time.
How to use this calculator
- Enter the distance traveled and the time it took.
A worked example
100 meters covered in 20 seconds → 100 ÷ 20 = 5 m/s.
400 meters covered in 50 seconds → 400 ÷ 50 = 8 m/s.
What the variables mean
| Variable | Meaning |
|---|---|
| Distance | Total distance traveled |
| Time | Time taken to travel that distance |
Edge cases worth knowing
This gives average velocity, not instantaneous velocity. A trip that sped up and slowed down along the way still returns a single average figure, not the speed at any one moment.
Zero time makes the result undefined — no distance can be covered in zero time at a finite speed, so the calculator returns no result rather than a division error.
Frequently asked questions
Is velocity the same as speed?
In everyday use, yes for a straight-line, one-direction trip — technically velocity also includes direction, while speed is just the magnitude.
Why is this “average” velocity rather than instantaneous?
Because it’s calculated from a total distance over a total time, it represents the average rate across the whole trip, not the speed at any single instant.
What if the distance is zero?
The calculator correctly reports zero velocity, since no distance was covered regardless of the time elapsed.
