1 Fig. 1 shows the velocity-time graph of a cyclist travelling along a straight horizontal road between two sets of traffic lights. The velocity, \(v\), is measured in metres per second and the time, \(t\), in seconds. The distance travelled, \(s\) metres, is measured from when \(t = 0\).

- Find the values of \(s\) when \(t = 4\) and when \(t = 18\).
- Sketch the graph of \(s\) against \(t\) for \(0 \leqslant t \leqslant 18\).
