Mirror physics help

    1. The problem statement, all variables and given/known data
    If you are walking towards a mirror at 7 m/s, how fast are you and your image approaching each other? Answer in m/s.


    2. Relevant equations
    ---


    3. The attempt at a solution
    I'm not sure how to solve this mathmatically but when I first looked at this question, I just automatically thought that the answer should be 7 m/s. Why or why not is that correct?

    Re: Mirrors

    Say you're 100m away from the mirror, in the image, how far away from the mirror (THROUGH) the mirror will your image be? use the mirror as a central point and then draw where you and your image are.
