Speed Calculator

Find speed from distance and time.

Distance

Time

Speed 10

Formula: speed = distance ÷ time

Step-by-step with your numbers:

1. Values used:

2. Distance = 100

3. Time = 10

5. Speed = Distance / Time = 100 / 10 = 10

Did we solve your problem today?

Calculate average speed from a distance travelled and the time it took.

The math behind it

speed = distance ÷ time. Convert m/s to km/h by ×3.6, or to mph by ×2.237.

100 m in 10 s → 10 m/s = 36 km/h = 22.4 mph.

Average vs instantaneous speed?

This gives the average over the whole trip, not the speed at a single moment.
