To determine the flow volume in gallons per minute, it’s essential to convert the collected amount from ounces into gallons and then adjust for the time frame of one minute. First, recognize that there are 128 ounces in a gallon. Thus, to convert ounces to gallons, divide the number of ounces by 128: \( 1700 \text{ ounces} \div 128 \text{ ounces/gallon} = 13.28125 \text{ gallons} \) Next, since the collection occurred over 90 seconds, we need to convert that time into minutes. There are 60 seconds in a minute, hence: \( 90 \text{ seconds} \div 60 \text{ seconds/minute} = 1.5 \text{ minutes} \) Now, to find the flow rate in gallons per minute, divide the total number of gallons by the time in minutes: \( 13.28125 \text{ gallons} \div 1.5 \text{ minutes} = 8.8520833 \text{ gallons/minute} \) This rounds to approximately 8.85 gallons per minute. Thus, this calculation demonstrates why this answer is correct: it accurately reflects the conversion of ounces
