I think if he is 'approaching his image at 4ms-1' then he is travelling at 4ms-1 because the image is on the mirror and the mirror isn't moving...I hope!

2m/s
because his image is travelling in the opposite direction but at the same speed so you just divide by 2

If the mirror's not moving, then it's a trick question using scientific notation.
It should just be 0.4 m/s. I could be wrong though, so double check it.
