The ratio of the numerical values of the average velocity and average speed of a body is always

A

Unity

B

Unity or less

C

Unity or more

D

Less than unity

Solution

(b) $\frac{{|{\rm{Average velocity}}|}}{{|{\rm{Average speed}}|}} = \frac{{|{\rm{displacement}}|}}{{|{\rm{distance}}|}} \le 1$

because displacement will either be equal or less than distance. It can never be greater than distance.
