Given the distance travelled, complete missing values on a speed-time graph Work out the speed \( v \) if the distance travelled is \( 50 \) miles. ![A speed-time graph. The vertical axis is labelled Speed (mph) and has no scale marked except for the letter v four squares up.
The horizontal axis is labelled Time (seconds) and the scale is 0, 1, 2, 3, 4 in even steps.
The graph consists of two sloped lines. The first is from (0,0) to (2, v) and the second is from (2, v) to (4, 0).]() \( 12.5 \mathrm{mph} \)
