8,520 gallons of water begins to drain at a rate of 12 gallons per minute. which equation can be used to find the number of minutes, m, it will take for the pool to be half full?

The time taken to drain water to be half full is 5 hours 55 min .

Step-by-step explanation:

Given as :

The total quantity of water pool = 8520 gallons

The rate of water drain = 12 gallons per min

The time taken to drain water to be half full = t min

Now, According to question

Time of water drain =

Or, time =

Or, time = 710 minutes

So, The time taken to full empty the pool = 710 minutes

Again, time taken to ran water to half full =

Or, t = 355 minutes

So, time taken to drain water to be half full = t = 355 min = 5 hours 55 minutes

Hence, The time taken to drain water to be half full is 5 hours 55 min . Answer
