12 gallons are filled in 1 minute.
Gallons filled in 60 mins = 12 x 60 = 720 gallons in 1 hour.
Total capacity of pool = 5760 gallons
720 gallons are filled in 1 hour.
Total Hours to fill 5760 gallons = \(\frac{5760}{720}\) = 8 hours.
Answer A...

Time Taken to fill = 5760/12 = 480 Min

Convert 480 min to Hrs=480/60=8

Hence A

The time required to fill the whole pool= \(\frac{5760}{12}\) minutes = 480 minutes

conversion from minutes into hours =\(\frac{480}{60}\) hours
=8 hours

1 minute = 12 gallons

=> 1 * 60 = 1 hour = 12 * 60 = 720 gallons

=> 8 hour = 720 * 8 = 5,760 gallons

To find the time it takes to fill the pool to capacity, we can use the formula:

time = amount of work / rate of work

In this case, the "amount of work" is filling the pool to its capacity of 5,760 gallons. The "rate of work" is 12 gallons per minute.

The amount of work is given in gallons, so we need to express the rate of work in gallons per hour. There are 60 minutes in an hour, so the rate of work is:

12 gallons/minute x 60 minutes/hour = 720 gallons/hour

Now we can plug in the values and solve for time:

time = amount of work / rate of work
time = 5760 gallons / 720 gallons/hour
time = 8 hours

Therefore, the answer is (A) 8.
