Apump is running at a rate of 6.4 quarts per minute. how many gallons per hour is this?

a. 192 gal / hr

b. 48 gal / hr

c. 96 gal / hr

d. 1536 gal /hr

A pump is running at a rate is 96 gal / hr.

Option (C) is correct .

Step-by-step explanation:

As given

A pump is running at a rate of 6.4 quarts per minute.

As 1 quarts = 0.25 gallons

   1 minute = 0.0166 hour

Now convert  quarts per minute into gallons per hour .

Rate = 96.4 gal/ hr(Approx)

Best estimate of rate is 96 gal / hr.

Therefore a pump is running at a rate is 96 gal / hr.

Option (C) is correct .

5.385164807

or

5.4

Step-by-step explanation:

Use the Distance Formula:

First, do (-4 - -2) exponent 2 + (2 - -3) exponent 2.

So you get: (-2) exponent 2 + (5) exponent 2.

Then, you do -2 times -2, since there is 2 as an exponent. You also do 5 times 5.

So you get: 4 + 25

Next, you add 4 + 25 and get 29.

Finally, you find the square root of 29, which is 5.385164807, or you can round it.

( I hope that is not too confusing. I couldn't do the exponents, so I just wrote it as a word. The whole thing was done with the Distance Formula.)
