Average = speed distance covered divided by travel time

You can calculate average speed using the equation: speed = distance ÷ time. Average speed cameras are used to find out if a motorist is driving too quickly. A distance-time graph shows how the distance of an object changes over time, and its speed.

Average speed

The speed of an object tells you how fast or slow it is moving. You can find the average speed of an object if you know:

The distance travelledThe time taken to travel that distance
