You can put this solution on YOUR website! When three pumps A,B, and C are running they can pump 3600 gal per hour.
When only A & B are running 2200 gal per hr can be pumped.
When only A and C are running 2400 gal per hour can be pumped.
What is the pumping capacity of each :
:
We can solve this easily with elimination
A + B + C = 3600
A + B + 0 = 2200
--------------------Subtraction eliminates A and B, find C
C = 1400 gal/hr
and
A + B + C = 3600
A + 0 + C = 2400
--------------------Subtraction eliminates A and B, find C
B = 1200 gal/h

I'll let you find A
