text: can you solve this??? hose #1 can fill a swimming pool in 6 hours. hose #2 can fill the same pool in 2 hours. hose #3 is identical to hose #1. if all three hoses are used to fill a pool, how long would it take?  explain. hose # 1 & #3 flow at a rate of 1/6 of a pool per hour. hose # 2 flows at a rate of 1/2 a pool per hour.  combining them you get 1/6 + 1/6 + 1/2 = 5/6 pool per hour. to get 1 pool full will take 6/5 of an hour or 72 minutes.
