Graphs in practical situations — practice question
The diagram presents the speed-time graph for the first $T$ seconds of a car journey. The vertical axis is marked Speed $(\text{m/s})$ and runs from $0$ to $12$, while the horizontal axis is labelled Time (seconds). The graph is a straight line from $(0,0)$ to $(10,12)$, followed by a horizontal segment at speed $12$ up to time $T$. The diagram is not drawn to scale.
