Two pumps

Pump A takes twice as long to fill a tank as B. Together, they take 2 hours to fill the tank. How long does each one take to fill the tank by itself?

Correct answer:

A =  6 h
B =  3 h

Step-by-step explanation:

A = 2B 1/A + 1/B = 1/2 1/A + 2/A = 1/2 3/A = 1/2 A=3 2=6 h
B=A/2=6/2=3=3 h  s=2 (A1+B1)=2 (61+31)=1
