Answer:
To find out how fast the Olympic-sized swimming pool is draining per hour, you can use the formula:
Draining Rate per Hour = Total Amount / Time
In this case, the total amount is 660,000 gallons of water, and the time is 110 hours.
Draining Rate per Hour = 660,000 gallons / 110 hours
Now, calculate:
Draining Rate per Hour = 6,000 gallons per hour
So, the swimming pool is draining at a rate of 6,000 gallons per hour.
Hope this helps :)
