    15/125 = t/72

    so, t = (72 x 15)/125 => 8.64 minutes

    i.e. 8 minutes and 38 seconds

    time=15 (72/125) = 8.64 minutes

    We can set up a ratio:

    (time) / (gallons) = (time) / (gallons)

    x / 72 = 15 / 125

    x = (15/125) * 72

    x = 3/25 * 72

    x = 216/25

    x = 864/100

    x = 8.64 minutes

    Okay, but maybe you want that in something a human would understand with some seconds? Let's take those 0.64 minutes and convert them to seconds.

    0.64 (minutes) * 60 (seconds/minute)

    = 38.4 seconds

    Answer:

    8 minutes 38.4 seconds

    125/15 = 8.333 (gallons per minute)

    72/8.333 = 8.6 minutes

    125 gallons takes 15 minutes

    1 gallon takes 15/125 minutes

    72 gallons takes 15x72/125 = 8.64 minutes.

      Probably because some people come late to answer, copy a correct answer, give everyone else a thumb down, and give themselves a thumb up in hopes their late answer will earn them points and possibly a best answer. Looking at the pattern I think it was Pinkgreen.
