If 1700 ounces of material is collected from nozzles in 90 seconds, how much is the total flow volume in gallons per minute?

To calculate the total flow volume in gallons per minute, we start with the amount of material collected, which is 1700 ounces over a time period of 90 seconds.

First, we need to convert the ounces collected into gallons. There are 128 ounces in a gallon. So, we can convert 1700 ounces to gallons by dividing by 128:

1700 ounces ÷ 128 ounces/gallon = 13.28125 gallons.

Next, we need to figure out the flow rate in gallons per minute. Since the collection occurred over 90 seconds, we need to convert those 90 seconds into minutes. There are 60 seconds in a minute, so:

90 seconds ÷ 60 seconds/minute = 1.5 minutes.

Now, we can find the flow rate by dividing the total gallons by the time in minutes:

13.28125 gallons ÷ 1.5 minutes = 8.8520833 gallons per minute.

Rounding this value gives approximately 8.85 gallons per minute, which corresponds to the choice provided. This calculation and conversion process demonstrates how the flow volume in gallons per minute relates directly to the amount collected in ounces and the timeframe of collection.
