How do I calculate speed if I only know distance and time?

Divide distance by time: Speed = Distance ÷ Time. For example, 120 km covered in 2 hours gives a speed of 60 km/h. Enter distance and time and leave speed blank to have this calculator work it out for you.

Can I use this for average speed on a trip with stops?

Yes, as long as you use total distance travelled and total elapsed time (including stops), the result is your average speed for the whole trip, not your speed while actually moving.

Speed, Distance & Time Calculator

Find speed, distance or time when you know the other two.

How this is calculated

Distance = Speed × Time

Assumptions used in this calculation

Units: Uses kilometres, hours and km/h; convert first if you have different units.
