If the aircraft's fuel consumption rate is 5.6 gallons per hour, how much fuel will it use on a flight of 230 nautical miles at an average groundspeed of 93 knots?

To determine the amount of fuel consumed during the flight, it's essential to first calculate the flight duration. The flight distance is given as 230 nautical miles, and the average groundspeed is 93 knots.

To find the flight time, we use the formula:

Flight Time (hours) = Distance (nautical miles) / Groundspeed (knots)

Substituting the provided values:

Flight Time = 230 nautical miles / 93 knots ≈ 2.47 hours

Next, to find the fuel consumed during this flight time, we multiply the flight duration by the fuel consumption rate:

Fuel Consumed (gallons) = Flight Time (hours) × Fuel Consumption Rate (gallons per hour)

Using the calculated flight time and the fuel consumption rate of 5.6 gallons per hour:

Fuel Consumed = 2.47 hours × 5.6 gallons/hour ≈ 13.8 gallons

This calculation yields approximately 13.8 gallons of fuel used for the flight, which aligns with the correct answer to the question. The method accurately incorporates both the aircraft's speed and fuel consumption to yield the correct amount of fuel for the specified flight distance.
