Physical Science

Remember!

speed = distance
time

Check the Units!
• If the distance is measured in metres and the time is measured in

seconds, the units will be m/s.
• If the distance is measured in kilometres and the time is measured in

hours, the units will be km/h.

Let’s Understand

Look at the graph.

Distance (m) 150

100

0 5 10 15

Time (s)

1 Describe the journey.

2 Work out the average speed for each part of the journey.

3 Think of a situation to fit the journey.

Now complete the activity in the Workbook.

Let’s Reflect

1 Explain what information you can get from a distance-time graph.

2 What formula do you need to know?
