1. (5.3) Water flows out from the bottom of a tank at a rate of r(t) = 200 - 5t liters per minute. (a) Find the amount of water that flows out from the tank during the first 10 minutes. (b) Find the amount of water that flows out from the tank during the first 2 hours. Hint: this question is a little tricky, and your first answer might not make sense. A good question to ask is, "What does it mean when r(t) = 0?" (c) What was the original amount of water held in the tank before any water flowed out
