Question

2. A plane mirror is approaching you at a speed of
10 cm/s. You can see your image in it. At what speed
will your image approach you?
(a) 20 cm/s
(b) 15 cm/s
(C) 10 cm/s
(d) 5 cm/s​

Answer 1

(C) 10 cm/s

If we stand at some height from mirror, then in the opposite of mirror we can say that same height is there, in that direction. So, I think it must be 10 cm/s.

Thanks!!!!
