Question

The janitor at a school discovered a leak in a pipe. The janitor found that it was leaking at a rate of 7 fl oz per minute. How fast was the pipe leaking in gallons per hour​? PLLLLLLLLLLLLZZZZZZZZZZZ

Answer 1

It leaks 420 gallons per hour.

Explanation:

7g/m

?/h

7/1 = x/60

(Cross Multiplication)

7 × 60 = x × 1

420 = x

It leaks 420 gallons per hour.

Answer 2

3.28 gallons per hour

Explanation:

Given that the pipe is leaking at a rate of 7 fluid ounce per minute, and that we need to determine the equivalent leaking rate in gallons per hour. It is important to establish the necessary conversion rates of fluid ounces (fl oz) to gallons (gal), and minutes to an hour.

1. Conversion rate for fluid ounces (fl oz) to 1 gallon (gal): 128 fl oz = 1 gal
2. Conversion rate of minutes to hour: 60 minutes = 1 hour.

Now that we have established the conversion rates, we can set up the following mathematical operations that will allow us to convert the leaking rate from fluid ounces per minute, to gallons per hour. We can express the conversion process in fraction form:

`((7 fl. oz.)/(min))` ×
`((1 gal)/(128 fl. oz.))` ×
`((60 min)/(1 hr))`

Start by multiplying the first two fractions together:

`((7 fl. oz.)/(min))` ×
`((1 gal)/(128 fl. oz.))` = 0.546875 gallons per minute, or 0.546875 gal/min

Next, multiply 0.546875 gal/min by 60 min/hr. This cancels out the "minute" as a unit of measurement, leaving you with gal/hr.

`((0.546875 gal)/(min))` ×
`((60 min)/(1 hr))` = 3.28125 gallons per hour, or 3.28 gal/hr.

Therefore, the pipe is leaking at a rate of 3.28 gallons per hour.
