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.
