Formula
Speed = distance/time; distance = speed×time; time = distance/speed.
Worked example
Speed Calculator example
100 km in 2 hours is 50 km/h.
How it works
Choose whether to solve for speed, distance, or time, then enter the two known quantities with consistent units. Miles and minutes are normalized before calculation.
