2. 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 r

DedPeter [7]

Answer:

Drain A $54\ min$

Drain B $21.6\ min$

Step-by-step explanation:

Let

x------> the time in minutes

y-----> the volume of the pool in gallons

we know that

The equation that represent the situation is equal to

$y=mx$

solve for x

$x=y/m$

Drain A

$x=y/m$

In this case we have

$m=2\frac{gal}{min}$

$y=108\ gal$

substitute

$x=108/2=54\ min$

Drain B

$x=y/m$

In this case we have

$m=5\frac{gal}{min}$

$y=108\ gal$

substitute

$x=108/5=21.6\ min$
