Answer:
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
<u>Now, According to question</u>
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
It has infinitely many solutions. The 4x's cancel themselves out and you are left with -5=-5, which is a true statement.
