Frequently asked questions

Divide the distance by the time taken. Travelling 120 km in 2 hours gives an average speed of 60 km/h.

Time equals distance ÷ speed, and distance equals speed × time. Rearrange the same relationship depending on what you know.

Divide the km/h value by 3.6. So 60 km/h is about 16.67 m/s, which the calculator also shows.

It is the average speed over the whole journey. Actual speed can vary along the way with traffic and stops.
