Speed, distance and time are tied together by one simple relationship: speed equals distance divided by time. This calculator lets you enter any two of the three and solves for the missing one, whether you need the average speed of a journey, the distance covered at a steady pace, or how long a trip will take. Keep your units consistent, for example kilometers and hours giving kilometers per hour, or meters and seconds giving meters per second, and the answer will match. It is handy for trip planning, running and cycling pace, physics problems and logistics. Because it works in any consistent unit system it is not tied to a single measure. Enter your two known values, press calculate, and the result appears instantly in your browser with nothing sent anywhere.
Speed equals distance divided by time. Rearranged, distance equals speed times time, and time equals distance divided by speed.
