    Question Word Problems

    One of my friends need help with a problem so i decided to give them a hand. Im not too sure about the answer given by his text book. Here is the problem.

    Gail and Bill drove to a beach at an average speed of 50mi/h. They returned home over the same road at an average speed of 55mi/h. The trip home took 30 min less time. How far is the beach from their home.

    Now i came up with the equation. Going 50(t)
    Return 55(t - 0.5)

    Now what i don't understand is, how are we able to find the distance if the amount of driving time has not been given? The book says 275mi.
