11. Oliver went for a ride on his bike.
Some of his journey is represented on the distance-time graph below.

Distance-time graph: distance travelled (miles) from 0 to 70 against time from 13:00 to 21:00. The line goes from (13:00, 0) to (15:00, 20), is flat to 15:30, rises to (16:00, 30), then to (17:00, 40), and is flat to 18:00

(a) What was Oliver’s average speed between 13:00 and 15:00? [2]

(b) Give an explanation for the shape of the graph between 17:00 and 18:00. [1]

(d)

Oliver started the final part of his cycle ride at 18:00.
He cycled 20 miles at an average speed of 8 mph.
Draw this part of the cycle ride on the distance-time graph. [2]
