If the aircraft has 50 gallons of fuel left and is cruising at 55 percent power, how long can it fly?

To determine how long the aircraft can fly with 50 gallons of fuel remaining while cruising at 55 percent power, it is essential to know the aircraft's fuel consumption rate at that power setting. Generally, when an aircraft operates at lower power settings, the fuel burn is reduced, allowing for extended flight duration.

In this case, if we assume that the aircraft's fuel consumption rate at 55 percent power is approximately one specific value (e.g., gallons per hour), we can calculate the flight time by dividing the total fuel available by the fuel consumption rate.

For instance, if the aircraft consumes 12.5 gallons per hour at 55 percent power, with 50 gallons of fuel, the calculation for flight time would be:

Flight Time (hours) = Total Fuel (gallons) / Fuel Consumption Rate (gallons per hour)

Flight Time = 50 gallons / 12.5 gallons per hour = 4 hours

This calculation aligns with the answer indicating 4 hours of flying time. Thus, if the aircraft has 50 gallons of fuel and is operating at 55 percent power, it can indeed fly for 4 hours before needing to refuel. This illustrates the relationship between fuel quantity, consumption rate, and
