(a) D Displacement can be zero, positive and negative.

(b) C Displacement can be equal to or less than the magnitude of distance travelled

(c) D Displacement is the shortest distance between two points. Distance is the total distance covered by the body while it travels between the two points. Therefore, displacement is always equal to or less than distance and hence their ration will be equal to or less than one.

(d) A When an object moves in one direction only, then distance is equal to the displacement.

(e) C The total distance covered by bill is 400+400 = 800 m
