A hose is running water into the pool at a constant rate of 60 gallons per hour. On one day, the hose was running for 3 hours, and the valve was left open for 6 hours. How much water is in the pool at the end of the day?
gallons

Answer 1

Answer:

12,680 gallons at the end of the day

Step-by-step explanation:

The valve that releases water into the cleaning tank is 20 gallons per hour. The hose that is running water into the pool is 60 gallons per hour.

60 gallons x 3 hours = 60 gallons from the hose.

20 gallons x 6 hours = 120 gallons from the valve.

60 + 120 gallons = 180 gallons.

12,500 = how much was at the start of the day

180 = how much was added

180 + 12,500 = 12,680

this should be correct! i hope this helps you!
