Question 147261
A Distillate flows into an empty 64-Gallon drum at spout A and out of the drum at
 spout B. If the rate of flow through A is 2 gallons per hour,how many gallons
 per hour must flow out at spout B so that the drum is full in exactly 96 hours?:  explain it.
:
Let x = gal/hr that must flow out of spout B
:
amt in - amt out = 64 gal
:
96(2) - 96x) = 64
:
192 - 96x = 64
:
-96x = 64 - 192
:
-96x = -128
x = {{{(-128)/(-96)}}} reduces to +{{{4/3}}}
