How to use Speed Calculator

Provide the distance and travel time, and the calculator will estimate the average speed implied by that trip.

What this calculator is for

This calculator is for travel planning, sports pacing, and physics problems when the full distance and elapsed time are known but speed still needs to be solved.

Tips

Average speed does not describe every moment of the trip, so it can differ from the highest speed reached along the way.
Include stops in the total time only if you want door-to-door average speed rather than movement-only speed.
