Speed Distance Time

Speed is a measure of how quickly something MOVES, so it is calculated by dividing distance by time.

Speed Distance Time Formulae

Speed, distance and time are all related by the formulae,

s = \dfrac{d}{t}s=

t

d

where SS is speed, dd is distance, and tt is time. You can rearrange this formula to find the other two, for example, if we multiple both sides by tt and divide both sides by ss, we get,

t = \dfrac{d}{s}t=

s

d

So, we can calculate the time by dividing the distance by the speed.

Typically, we measure distance in metres (mm), kilometres (kmkm), or miles, and we measure time in seconds (ss), minutes (mins) or hours (hh). As a result, the units we USE to measure speed are compound units e.g m/sm/s or km/hkm/h
