The diagram presents the speed-time graph for the first 100 seconds of a journey made by a car and a motorbike.
Diagram text: The vertical axis is labelled "Speed (m/s)" and extends to 20. The horizontal axis is labelled "Time (s)" and extends to 100. A solid line marked "Car" remains at 18 m/s from 0 to 60 s, then drops in a straight line to 6 m/s at 100 s. A dashed horizontal line labelled "Motorbike" is drawn at 12 m/s.
