(a(i))[1]
From Fig. 1.1, find the distance separating A and B when $t = 20\,\text{s}$.
(a(ii))[1]
From Fig. 1.1, work out how much longer A and B took to complete the race.
(b(i))[2]
Cyclist C starts at the same moment as A and B and travels the first 200 m of the race at a steady speed of $5.0\,\text{m s}^{-1}$. He then speeds up and completes the race at $t = 60\,\text{s}$. On Fig. 1.1, sketch the distance-time graph for cyclist C.
(b(ii))[2]
Calculate the average speed of cyclist C over the entire race.
