Question 147267
Let x=required rate of flow out of the drum
Then 2-x=net rate of flow into the drum (rate of flow in - rate of flow out)
So, our equation to solve is:
(2-x)*96=64 or 
192-96x=64
-96x=-192+64
-96x=-128
x= 1/1/3  or 4/3 gal/hr

CK
2-4/3=2/3 gal/hr --net rate of flow into the drum
So, 2/3 * 96=64
64=64
