    First, change everything into minutes.

    12 noon is 12 by 60 which = 720 minutes.

    9am is 9 by 12 which = 540 minutes.

    X is now your number of minutes before noon. So noon - x is the next step:

    720 - x

    20 minutes ago it was 720 - x - 20

    720 - x - 20 = 540 + 3x (3x because you're looking for 3 times as many minutes)

    720 - 20 - 540=4x (you combine all the like numbers and variables)

    160 = 4x

    160/4 = x

    40 = x

    Your answer is 40 minutes
