<PRE><B>Question 1101758</B>
1/8 as many faucets will fill 1/8 as many tubs
in the same amount of time, so
2 faucets will take 10 hrs to fill 1 tub
-------------------------------------------
6 times as many faucets will take 1/6 the time
to fill the same number of tubs, so
12 faucets will take 10/6 hrs to fill 1 tub
-------------------------------------------
With the same number of faucets, it will take
9 times as long to fill 9 times as many tubs, so
12 faucets will take 90/6 hrs to fill 9 tubs
--------------------------------------------
90/6 = 15
12 faucets will take 15 hrs to fill 9 tubs
---------------------------------------
get a 2nd opinion if needed
