Consider a water reservior. The resrvoir graduallly loses water, because people insist on showering, washing clothes, etc. The "use rate" R is the rate at which consumers use the water. On April 13, between 1pm and 2pm, R is 5-gallons per second. How much water was drained from the reservoir between 1pm and 130pm? At midnight, when everyone was asleep, a big industrial water user suddenly becomes active. Let A denote the amount of water taken from the reservoir (in gallons), with A = 0 at midnight. It turns out that A=2t2 with t expressed in seconds. Given this information, calculate R, the use rate, at t = 10 s.
