Are the magnitudes of average velocity and average speed equal?

STATEMENT-1: When a particle move along a straight line magnitude of its average velocity is equal to its average speed over any time interval provided particle does not return to path. STATEMENT-2: For one dimensional motion displacement and distance both are same.

Assertion: The average velocity of a particle is zero in a time interval. It is possible that the instantaneous acceleration is never zero in the interval. Reason: The magnitude of average velocity in an interval is equal to its average speed in that interval.

Assertion : Magnitude of average velocity is equal to average speed, if velocity is constant. Reson : If velocity is constant, then there is no change in the direction of motion.

Statement-2: It is possible when the direction of motion keeps changing. Statement-1: Magnitude of average velocity is equal to average speed, if velocity is constant.

Under what conditions (s) is the magnitude of average velocity of an object equal to its average speed ?

Assertion: Average speed in an interval cannot be less than the magnitude of average velocity in the same interval Reason: For a particle in motion distance travelled is always greater than or equal to the magnitude of the displacement.
