What is relative position?

The position of a body with respect to something fixed is called relative position.It is correlated to Einstein's Theory of relativity that everything in this universe is relative in nature.

A car moving from a point is said to cover a distance relative to the starting point Here the starting point of the car is taken as the reference point to measure the distance covered by the car. Had the starting point not fixed we would not be able to calculate the distance travelled by it. So the distance covered by the car is relative to its starting point. SINCE in this case the starting point is at zero the relative distance covered by the car is the actual distance covered by it otherwise we need to subtract it
