Q15MKinematicsFree sample

Fig. 1.1 shows the distance-time graph for a journey made by a cyclist between town A and town B.

The cyclist leaves town A at time t=0t = 0 and arrives at town B at t=4.0 hourst = 4.0\ \text{hours}.

(a)
(i)

Determine the distance between the two towns.

distance=______\text{distance} = \_\_\_\_\_\_
1M
(ii)

Determine the time for which the cyclist rests during the journey, before he reaches town B.

time=______\text{time} = \_\_\_\_\_\_
1M
(b)

The speed of the cyclist near the end of the journey is greater than the speed at the beginning.

State how the graph shows this.

1M
(c)

Calculate the average speed of the cyclist for the journey from A to B.

average speed=______\text{average speed} = \_\_\_\_\_\_
2M
