Distance, speed and time are related by a simple linear equation, distance (d) = speed (s) multiplied by time (t). If given any two of the variables, you can solve for the missing third variable, using one step of algebraic manipulation if necessary.

There can be many different units for each of these variables and to apply the equation correctly, the units of the variables must correspond correctly. For instance, if distance is given in miles and time in hours, then the speed must be in miles per hour.

Firstly make sure your units for distance and speed correspond correctly. If not, convert your units. For example, if your distance is in metres but your speed in kilometres per hour, you should convert your distance into units of kilometres.

The basic linear equation that relates distance, speed and time is given by D = S X T, where D stands for distance, S stands for speed, and T stands for time. Plug in the given values for distance and speed, using the appropriate units.

Divide both sides of the equation by the rate. The resulting value on the left side of the equation will be time, given in the same units as the time element of your speed.
