Hi....
x’ = -x, where x is position of observer and x’ is position of the image.
With mirror at 0.
So, if dx/dt = 2 m/s, dx’/dt = -dx/dt = - 30m/s.
using the classical formula for relative speed,
Vrel = dx’/dt - dx/dt = -2dx/dt = -60m/s.
So, the image is approaching the observer at 60 m/s.
Hope this helps u!!
