Fill it up!

  1. Jan 10, 2007 #1
    A large water tank has two inlet pipes (a

    large one and a small one) and one outlet

    pipe. It takes 2 hours to fill the tank

    with the large inlet pipe. On the other

    hand, it takes 6 hours to fill the tank

    with the small inlet pipe. The outlet

    pipe allows the full tank to be emptied

    in 8 hours.

    What fraction of the tank (initially

    empty) will be filled in 1.85 hours if

    all three pipes are in operation? Give

    your answer to two decimal places (e.g.,

    0.25, 0.5, or 0.75).

    It should be full (1.00) and some had already been spilled.
