This diagram is a speed-time graph covering the last 40 seconds of a car journey. The vertical axis is labelled Speed (m/s), and the horizontal axis is labelled Time (seconds). At $t=0$, the speed is $v$. From 0 to 24 seconds, the speed rises in a straight line to $v+10$. From 24 to 40 seconds, the speed falls in a straight line to 0. The diagram is marked NOT TO SCALE.
