                                               A car travelling with a speed of \[\text{7}0\text{ km }{{\text{h}}^{\text{-1}}}\] on a straight road is ahead of a motor-cycle travelling with a speed of \[80\text{ km }{{\text{h}}^{\text{-1}}}\]. How would the relative velocity be altered if motor-cycle is ahead of car?

Answer:

                The relative velocity will not alter at all, since it is independent of the positions of bodies.
