Final answer:
To convert 3 quarts per minute to gallons per hour, first convert quarts to ounces, then convert ounces to gallons, and finally convert minutes to hours.
Step-by-step explanation:
To convert quarts per minute to gallons per hour, we need to convert the units so that they are the same. First, convert 3 quarts to ounces. There are 32 ounces in a quart, so 3 quarts is equal to 96 ounces. Next, convert ounces to gallons. There are 128 ounces in a gallon, so 96 ounces is equal to 0.75 gallons. Finally, convert minutes to hours. There are 60 minutes in an hour, so 1 minute is equal to 1/60 of an hour. Therefore, 3 quarts per minute is equal to 0.75 gallons per hour.
