Storm sewer backup causes your basement to flood at the steady rate of 1 in. of depth per hour. The basement floor area is \(1500 \mathrm{ft}^{2}\). What capacity (gal/min) pump would you rent to

(a) keep the water accumulated in your basement at a constant level until the storm sewer is blocked off, and

(b) reduce the water accumulation in your basement at a rate of \(3 \mathrm{in}\)./hr even while the backup problem exists?
