Question 388415: a larger pipe can empty a pool for 6 hours A smaller pipe can empty the same pool for 9 hours. How long will it take for both pipes to empty the pool? (Show Your Solution) Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! The larger empties 1/6 per hour.
The other empties 1/9 per hour.
Add those, total per hour.
The inverse = hours/total.
