Question

1. A pool company is trying out several new drains. Drain A empties a pool at a rate of 2 gal/min. Drain B empties a pool at a rate of 5 gal/min. One pool has 108 gal of water in it. Write an equation for each drain that shows the amount of time it takes to empty the pool. Then solve each equation showing your work.

Answer 1

The equations we can create is based from this equation:

time = volume of pool / rate

Drain A: time = 108 gal / (2 gal / min) = 54 min

Drain B: time = 108 gal / (5 gal / min) = 21.6 min
