Question 1061623
inlet pipe will fill the pool in 34 hours.  Every hour, it fills 1/34 of the pool
Outlet pipe will empty the pool in 35 hours.  Every hour, it empties 1/35 of the pool.
In x hours we want 1/2 the pool to fill, since half is already filled.
We want (x/34)-(x/35)=1/2
multiply by 1190 both sides, the LCD.
35x-34x=595 (1190/2)
x=595 hours
in that time 595/34-595/35=0.5
