The following table gives the displacement of a car at different instants of time.  

Time (s) 0 1 2 3 4
Displacement (m) 0 5 10 15 20
  1. Draw the displacement-time sketch and find the average velocity of the car.
  2. What will be the displacement of the car at (i) 2.5 s and (ii) 4.5 s?

Figure (a) shows the velocity-time graph for the motion of a body. Use it to find the displacement of the body at t = 1 s, 2 s, 3 s and 4 s, then draw on Figure (b), the displacement-time graph for it.
