In the pool problem above how long would it take to fill the pool if the drain, which could drain the pool in 15 hours, is left open?
I have the first part figured out but I am struggling with the second part. If you could just set up the table for me that would be great! Thanks! Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! The time required to fill a pool with a water hose is 30 hours. Using a pump the pool can be filled in 10 hours. How long will it take to fill the pool using a pump and 2 hoses?
