[a] The cyclist was stationary from 1.5 to 2 hours and from 3 to 4 hours: 0.5 + 1 = 1.5 hours.[b] He travelled 35 miles from home and 35 miles back: 35 + 35 = 70 miles.[c] The return journey took 6.5 − 4 = 2.5 hours. His speed was 35 ÷ 2.5 = 14 mph.[d] The steepest section was from 2 to 3 hours, when he travelled from 15 to 35 miles from home. His greatest speed was (35 − 15) ÷ (3 − 2) = 20 mph.
