The pool

The pool contains 220 m3 of water. The pool can be emptied either:
a) 10 hours of pipe B and 8 hours of pipe A, or
b) 10 hours of pipe A and 7 hours of pipe B.

How many cubic meters of water will flow in 1 hour from pipe A and how many from pipe B?

Correct answer:

A =  15
B =  10

Step-by-step explanation:


10•B + 8•A = 220
10•A + 7•B = 220

8A+10B = 220
10A+7B = 220

A = 15
B = 10
