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
Now, According to question
Time of water drain = [tex]\dfrac{\textrm total quantity of water in pool}{\textrm rate of water drain}[/tex]
Or, time = [tex]\dfrac{\textrm 8520 gallons}{\textrm 12 gallons per min}[/tex]
Or, time = 710 minutes
So, The time taken to full empty the pool = 710 minutes
Again, time taken to ran water to half full = [tex]\dfrac{710}{2}[/tex]
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
