Answer:
Explanation:
From the graph, the initial distance of the cyclist decreases with time before it starts to increase at the same rate.
i. When t = 60 minutes,
distance = (60 -60)
= 0
ii. When t = 120 minutes,
distance = (120 -60)
= 20 km
This implies that the endpoint of the cyclist's race was 20 km from the water station which took 60 minutes. So that on meeting the endpoint, the cyclist cycled back towards the water station at the same rate.
