Answer 2

Answer:

4 m/s

Explanation:

In this question,

We have been given that A man approaches a vertical plane mirror at a speed of 2 m/s.

We need to find at what rate does the man approach his image

The Rate at which man approach his image = Rate at which man is approaching the mirror + rate at which man's image is approaching

The Rate at which man approach his image =  2 + 2

The Rate at which man approach his image = 4 m/s
