If an airplane is consuming 14.8 gallons of fuel per hour at a cruising altitude of 7,500 feet, how much fuel will it consume in 3.4 hours?

To determine the total fuel consumption, you can use the formula:

Total Fuel Consumption = Fuel Burn Rate (gallons per hour) × Time (hours)

In this case, the fuel burn rate is 14.8 gallons per hour, and the time is 3.4 hours.

Calculating this gives:

Total Fuel Consumption = 14.8 gallons/hour × 3.4 hours = 50.32 gallons

The closest result to this calculation is the option indicating 50.32 gallons, which represents the actual fuel consumption during the specified duration. This highlights the importance of careful calculation when determining fuel needs for flight planning, ensuring that pilots have a reliable understanding of their fuel requirements over time to maintain safety and efficiency during operations.
