A sump pump in my basement kicks on automatically when the water level reaches a certain depth and turns off automatically when the depth is down to 0. One rainy night, water began to accumulate in the basement at 12:00 midnight, rising at a constant rate. The sump pump turned on at 7:30 AM and began pumping at a constant rate. At 8:00 AM the water depth was 2 inches, and water stopped coming into the basement. By 10:30 AM all the water had been pumped out.
a. Using r in./h for the rate of water accumulation and s in./h for the rate at which it is pumped out, write an equation modeling the situation at 8:00 AM
b. Using the rest of the info, find the s
c. Find the rate r at which water had been accumulating
HELP!! I can't even figure out a, let alone the rest of them...
