Answer 1

The answer is A.....

Answer 2

a. 67.5

Explanation:

∵ 1 qt = 0.25 gallon

Also, 1 hour = 60 minutes,

⇒ 1 minute =
`(1)/(60)` hour,

`\implies 4.5\text{ qt per minute}`

`=(4.5* 0.25)/((1)/(60))\text{ gal per hour}`

`=4.5* 0.25* 60\text{ gal per hour}`

`=67.5\text{ gal per hour}`

Hence, option 'a' is correct.
