Chapter 13.3, Problem 9P

1. Measure how fast water comes out of some faucet of your choice. Give your answer in gallons per minute, and explain how you arrived at your answer. (You do not have to till up a gallon container to do this.)
2. Figure 13.35 shows a bird’s-eye view of a swimming pool in the shape of a cross (four 10-ft-by-10-ft squares surrounding a 10-ft-by10-ft square). The pool is 4 ft deep but doesn’t have any water in it. There is a small faucet on one side with which to till the pool. How long would it take to fill up this pool, assuming that the water runs out of this faucet at the same rate as water from your faucet? Use the fact that 1 gallon is about 0.134 . Explain your answer.
