What is the required amount of AvGas for a flight under the given conditions if it demands 67 gallons?

To determine the required amount of AvGas (aviation gasoline) for the flight, it is essential first to convert the gallon requirement into a time representation based on fuel consumption rate.

If the flight demands 67 gallons of AvGas, and the flight time is given as hours and minutes, we need to find the fuel burn rate of the aircraft in gallons per hour. The correct answer aligns with a specific fuel consumption pattern that relates to the total gallons needed and time.

Selecting an answer of 6 hours and 39 minutes suggests a relatively fuel-efficient operation, where the aircraft can maintain the necessary speed and altitude over time with moderate fuel consumption. Here, if you were to perform calculations based on standard fuel consumption rates, you could arrive at approximately this time frame given the total number of gallons consumed.

When analyzing the other options, they might represent different flight durations that do not align with standard fuel consumption rates or the total gallons needed. The chosen response also allows for a practical margin, making it reasonable for most flight operations under normal conditions, thus confirming that 6 hours and 39 minutes is a plausible estimate for the required amount of fuel based on the given conditions.
