Question

The ratio of the magnitude of average velocity to average speed of a body in motion can be ________ one.

• A. less than
• B. equal to
• C. greater than
• D. none of these

Answer 1

Answer: (A), (B)

The correct options are
A less than
B equal to

Average velocity $V_{avg}=\frac{Displacement}{time}$

Average speed $u_{avg}=\frac{Distance}{Time}$

Since magnitude of displacement of the body can be either less than or equal to the distance travelled by the body. So ratio of magnitude of average velocity to average speed of a body in motion can be less than or equal to one.
