Question

Two persons travel from a point A to a point B, one by train and the other by aeroplane. which of the following are equal for them? a) distances b) displacements c) both (a) and (b) d) neither (a) nor (b)

Answer 1

well if we consider that the path covered by the train and aeroplane is a straight line between A and B then we can say that
Distance and displacement are equal for them 
but if train follows a different path and aeroplane follows a different path at such case we can say that only displacement is same 
since displacement is the shortest distance between two points here as the initial and final point is same for both aeroplane and train their displacement are same 
Hope this helped you
