It's hard to imagine that I was swimming in our pool on Friday when it was so hot and then the weather changed.  That meant I had to drain water out of our pool and put on the winter cover.  When I put the hose in the pool to drain the water out, I noticed that the pool level went down 1 inch in 1 hour.  If I started to drain the pool at 7:00 a.m. in the morning, at what time can I take the hose out of the pool if I want the level of the pool to go down 1 foot?

Extra Challenge (for 5th graders or those who would like to try): Do the same problem above except instead of 1 inch in 1 hour, change to 2 inches in 1 hour. Also change from 1 foot to
1 1/4 feet.
