Question

A standard shower drain

Answer 1

Answer:

see the explanation

Step-by-step explanation:

The given rate is

$480\ \frac{gal}{h}$

Create three different rates, that are all  equivalent to this rate

First rate

1,440 gallons in 3 hours

Find the units rate

Divide the total volume by the total time

$\frac{1,440}{3}=480\ \frac{gal}{h}$

Second rate

960 gallons in 120 minutes

Find the units rate

Divide the total volume by the total time

Convert minutes to hours

$120 \ min=2\ h$

$\frac{960}{2}=480\ \frac{gal}{h}$

Third rate

720 gallons in 1.5 hours

Find the units rate

Divide the total volume by the total time

$\frac{720}{1.5}=480\ \frac{gal}{h}$

Convert gal/h to gal/min

Remember that

$1\ h=60\ min$

$480\ \frac{gal}{h}=480/60=8\ \frac{gal}{min}$
