The ratio of the numerical values of the average velocity and average speed of a body is always
The ratio of the numerical values of the average velocity and average speed of a body is always
Unity
Unity or less
Unity or more
Less than unity
The ratio of the numerical values of the average velocity and average speed of a body is always
$\frac{{|{\rm{Average velocity}}|}}{{|{\rm{Average speed}}|}} = \frac{{|{\rm{displacement}}|}}{{|{\rm{distance}}|}} \le 1$
because displacement will either be equal or less than distance. It can never be greater than distance.
