Question 1153927
<br>
Since the faster pump works 3 times as fast as the slower, in filling the tank the faster pump does 3/4 of the work and the slower pump does 1/4.<br>
The faster pump fills 3/4 of the tank in 12 minutes; the time it would take that pump alone to fill the tank is 12*(4/3) = 16 minutes.<br>
The slower pump fills 1/4 of the tank in 12 minutes; the time it would take that pump alone to fill the tank is 12*4 = 48 minutes.<br>
ANSWERS:
Faster pump alone: 16 minutes
Slower pump alone: 48 minutes<br>
