We need to turn 120 gallons per minute to quarts per hour. We can do this by using two conversion factors. First turn 120 gallons to quarts. Before we do that, we need to find out how many quarts there are in 1 gallon. So 1 gallon= 4 quarts. Now that we know this, lets setup our conversion factor.
[tex] \frac{120 gallon}{minute} * \frac{4 quarts}{1gallon} = 480\frac{quarts}{minute}[/tex]
Now that we know 120 gallon/minute is 480 quarts/minute, time to turn minutes to hours and find out how many quarts per hour So lets use another conversion factor. First we need to convert minutes to hours. To do this, we need to know how many minutes there are in 1 hours. 1 hour = 60 minutes. Ok let setup our conversion factor. Let get the 480 quarts per minute and turn it to hour.
[tex] \frac{480 quarts}{1minute} * \frac{60 \sout{minutes}}{1hour} = 28,800\frac{quarts}{hour}[/tex]
The answer is 28,800 quarts per hour
