Question 1023738: Hello Tutors,
Please help me solve this rational expression word problem.
When water is turned on and passes through a small hose, your pool can be filled in 8 hours. When the water is turned on at two spigots and passes through both the small and large hose, the pool can be filled in 4 hours. How long would it take to fill the pool using only the large hose?

Rates are unit of POOL per HOUR
HOSE              RATE
small             1/8
large             1/x
small&large       1/4
