Simple speed of light problem

    [SOLVED] Simple speed of light problem

    1. The problem statement, all variables and given/known data
    How long does it take light to travel trough a 5.23-mm-thick piece of window glass?

    Trough what thickness of water could light travel in the same amount of time?

    2. Relevant equations

    3. The attempt at a solution

    I thought I could just do the speed of light divided by the thickness to get my seconds but thats not right so can someone please help me?
