Assertion: The average speed of an object is greater than or equal to the magnitude of the average velocity over a given time interval. Reason: The two are equal only if the path length is equal to the magnitude of displacement.

In one dimensional motion the two quantities are equal only because the object does not change its direction during the course of motion. In all other cases, the path length is greater than the magnitude of displacement.
