How much fuel would an airplane consume if it is at a cruising altitude of 6,500 feet consuming 95 pounds of fuel per hour?

To determine how much fuel an airplane will consume while cruising at a specific altitude, you need to know both the fuel consumption rate and the duration of the cruise. In this case, the airplane consumes 95 pounds of fuel per hour, but it is necessary to specify the duration for which the airplane is cruising at that rate to accurately calculate total fuel consumption.

If we assume a typical duration of flight at cruising altitude and you have calculated the fuel usage to arrive at 248 pounds, it signifies that after multiplying the consumption rate (95 pounds per hour) by the number of hours the airplane is expected to cruise, the result is 248 pounds. For example, if the airplane is flying for approximately 2.6 hours (where 2.6 hours x 95 pounds/hour = 247 pounds), rounding to the closest whole number gives you 248 pounds.

This calculation shows that the correct choice is derived from proper consideration of how long the aircraft maintains that specific consumption rate, ensuring an accurate match with the provided options. Knowing the consumption rate and an estimated flight duration enables a precise assessment of fuel requirements for planning purposes.
