Suppose you walk towards a mirror at 1.0m/s.How fast do you and your image approach each other?Explain how you arrive at your answer

### 1 Answer | Add Yours

we and image approach each other at speed of 2m/s.

Let distance between you and mirror = x meters.

so image formed behind the mirror at distance of x meters.

Now distance between you and your image = 2x meters.

let you have taken time to reach mirror = t sec.

so speed =x/t m/sec.

But image covered distance =2x in tsec.

so speed=2x/t m/sec.
