The State conservation department has a constructed a large fish hatchery. It is shapep like a rectangle and measures approximately 35.5 meters wide, 61 meters long, and
the water level is normally 4 meters deep. During the care of the fish, the water depth
varies, and one day the manager asks you to add 9 inches of water to the depth of the
hatchery to bring it up to normal level using a high-speed hose that fills at an average
rate of 60 gallons/minute. After you complete that task, the manager wants you to add
a treatment of 1.5 lbs of chemical per 10,000 cubic feet of water.
