Final answer:
To find the pumping rate, divide the total volume of gas by the time it took to pump. The gas pump's rate is 5.23 gallons per minute.
Step-by-step explanation:
The student is looking to determine the pumping rate of gas in gallons per minute. To calculate this, we divide the total volume of gas by the total time it took to pump that volume. So the pumping rate is given by the formula:
Rate = \(\frac{Total Volume}{Total Time}\)
Inserting the values provided:
Rate = \(\frac{18.3 \text{ gal}}{3.5 \text{ min}}\) = 5.23 \text{ gal/min}
Therefore, the gas pump delivers gas at a rate of 5.23 gallons per minute.
