Answer

Time (s)	0	1	2	3	4
Displacement (m)	0	5	10	15	20

(a) The displacement-time sketch for the car is shown below:

As we know,

Avg. velocity of car = $Total\ distance \over Total\ Time$

= $20 - 0 \over 4 - 0$

= $20 \over 4$

= 5 ms^-1

Hence, the average velocity of the car is 5 ms^-1.

(b) When we observe the graph, we can find the displacement of the car at various points,

At t = 2.5 s, displacement = 12.5 m and

At t = 4.5 s, displacement = 22.5 m
