It comes at a spped of 2*1 ms=2 ms
because velocity is incident at at speed v
then it comes back it is -v sice velocity is a vector
so net=v-(-v)=2v
But y 2???

Velocity of boy ()= 1 m/s
velocity of image () = -1 m/s
(-ve sign is there as its direction is opposite to that of the boy)

Relative speed between boy and image =

So the image will approach him at 2 m/s.
thanks
nice dear bro
