    time word problem

    Hi all;
    I'm trying to solve the following problem I know the answer is 5hours I just need to know if I'm solving right.


    Wilbur left the hardware store and traveled
    toward the recycling plant at an average
    speed of 33 km/h. Mary left two hours later
    and traveled in the same direction but with
    an average speed of 55 km/h. How long did
    Wilbur travel before Mary caught up?

    I've got (3)33 + 33(x) = 55 + 55(x) resulting x=2 which does result in 5hours is this right?

    Thanks.

    t = time in hours wilbur travels

    t - 2 = time in hours mary travels

    wilbur's distance traveled = mary's distance traveled

    33t = 55(t-2)

    solve for t
