    Answer: 25 psi

    250 / 50 = 5 sections, and 5 x 5 psi = 25 psi.

  2. A water tank holds 1,200 gallons and drains at 80 gallons per minute. How long until it is empty?

    Answer: 15 minutes

    1,200 / 80 = 15 minutes.

    Answer: 25 feet

    By the Pythagorean theorem, sqrt(24^2 + 7^2) = sqrt(625) = 25 feet.

  5. A pump moves 300 gallons in 4 minutes. At this rate, how many gallons does it move in 10 minutes?

    Answer: 750

    300 / 4 = 75 gpm, and 75 x 10 = 750 gallons.
