A woman travels by car from town A to town B, pausing at a garage on the way. The journey is represented by the distance-time graph in Fig. 3.1. Fig. 3.1 plots distance in km against time in hours, beginning at town A (0 km) and finishing at town B(100 km), with a horizontal section showing the car is stationary.
(a(i))[1]
Determine the overall time taken for the journey.
(a(ii))[1]
Determine how long the car remains stationary.
(a(iii))[1]
Determine the distance from town A to town B.
(a(iv))[3]
Calculate the average speed of the car from 0 to 0.75 h.
(b)[2]
Describe the difference in speed and explain how Fig. 3.1 shows this on the graph.
