Question

Usable Fuel (just number)

A)48,100lbs
B)46,052 lbs
C)42,090lbs
D)47,060lbs

Answer 1

The correct amount of usable fuel depends on factors like energy content, weight of fuel, and vehicle fuel efficiency. Reference information provides examples of fuel economy and total fuel mass, but without context, determining the exact answer among the options is not feasible.

Step-by-step explanation:

To answer the question about the usable fuel, we need to consider several factors provided in the reference information, such as the energy content of fuel, the weight of the fuel, and the fuel efficiency of the vehicle. Reference to 300 gallons times 2.85 kg/gal suggests a total fuel mass of approximately 850 kg.

However, we must also consider the factor of necessary energy to lift the fuel, indicating that we've underestimated the fuel required if the vehicle is an aircraft.

Using the provided reference information, such as energy content and fuel efficiency, we can deduce the correct amount of usable fuel.

For example, long-haul trucks with a fuel economy of 6 miles per gallon and carrying 150 gallons per tank have a range of about 2000 miles. However, without a specific context or additional data, it's challenging to derive a definitive answer to the question of the usable fuel amount among the given choices.

Answer 2

The amount of usable fuel in a Boeing 747 generally ranges from approximately 215,000 to 240,000 pounds. Option C is answer.

Explanation:

The usable fuel capacity of a Boeing 747 varies based on factors such as the specific model, modifications, and airline preferences. Typically, the fuel capacity of a Boeing 747-400, one of the most common variants, is around 57,285 gallons. Considering the density of Jet-A fuel, which is about 6.7 pounds per gallon, the usable fuel weight can be estimated. This results in a range of approximately 215,000 to 240,000 pounds of usable fuel for a Boeing 747.

It's important to note that airlines adjust the amount of fuel loaded based on factors like the planned route, payload, and regulatory requirements to ensure optimal efficiency and safety for each flight.

Option C is answer.
