The speed formula
In uniform motion speed equals distance divided by time: v = s / t. From this, distance s = v × t and time t = s / v.
How it is calculated
Formula
v = d ÷ t (speed); d = v × t (distance); t = d ÷ v (time). Units: km, h, km/h.
Example
120 km, 1.5 h → 80 km/h. 80 km/h × 2 h → 160 km.
Frequently asked questions
How do I calculate average speed?+
Average speed is distance divided by time: v = d ÷ t. For example, 120 km in 1.5 hours is 80 km/h.
How do I calculate travel time?+
Time is distance divided by speed: t = d ÷ v.
