Answer to: The graph given alongside shows the positions of a body at different times. Calculate the speed of the body as it moves from : (i) A to B, (ii) B to C, and (iii) C to D.

(i) The distance covered from A to B is ( 3-0) = 3 cm Time taken to cover the distance from A to B = (5 -2) = 3s Speed = Speed = = 1 cm/s ...
