To describe the position of an object, reference point have to be specified.

A car moving along straight line covers $\frac{1}{5}th$of total distance with speed $v_1$ and remaining part of distance with speed$v_2$ . The average velocity of car over entire distance is

A body on an inclined plane slides down $\frac{1}{4}th$ of distance in 2 seconds. It will slide down the complete distance along the plane in (the inclined plane have zero friction)

Under what conditions is the resultant displacement of a body zero even when it travels a certain distance? Explain with an example.
