its distance–time graph. These graphs always have time on the X-axis. We can think of them as telling a story: what happened first, second, etc. This graph tells us that in 5 seconds an object travelled 40 metres. Because speed = distance ÷ time, we can use values from the graph to calculate the speed: 40 ÷ 5 = 8 Speed = 8m/s
Question 1: Calculate the average speeds for each of the following, without using a calculator. (a) A car travels 60 miles in 2 hours (b) A lorry travels 120 miles in 3 hours
Kristina’s journey is shown on the distance-time graph below. (a) Work out Kristina’s average speed, in kilometres per hour. (b) Use the information to plot Lucas’s journey on the same distance-time graph.
So, we can calculate the time by dividing the distance by the speed. Typically, we measure distance in metres (m), kilometres (km), or miles, and we measure time in seconds (s), minutes (mins) or hours (h). As a result, the units we use to measure speed are compound units e.g m/s or km/h.
