Answer:
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Rearranging the formula
The formula speed = distance ÷ time can be rearranged, just like any other equation.
The formula can be rearranged in three ways:
speed = distance ÷ time
distance = speed × time
time = distance ÷ speed
To calculate one of the variables (speed, distance or time) we need the other two.
For example, to find the time taken to make a journey, we need the length of the journey and the speed of travel.
