Question

Alex uses a pump to fill 15,000 quarts of water in 5 minutes.
He can fill 6,000 gallon of water in minutes.

• A. 7
• B. 6
• C. 8
• D. 9

Answer 1

The correct option is C 8

$\text{Alex fills 15,000 qt water in 5 minutes.}$

In 1 minute, he can fill = 15,000 $÷5$
= 3,000 qt

Now we have to find the time taken to fill 6,000 gallons of water.

$\text{Let's convert}$ $\text{gallon to quartz.}$

$\text{We know that,}$
$\text{1 gallon =}$ $\text{4 quarts}$


$\text{So we will multiply 6,000 with 4.}$

$\text{6,000 gal = 6,000}\times \text{4 qt}$
$=24,000\text{qt}$

$\text{Now 24,000 qt water will be filled in}$
$\text{= 24,000}÷\text{3,000}$
$\text{8 minutes}$

$\text{Hence, Alex will take 8 minutes}$ $\text{to fill 24,000 quarts of water.}$
