A Boeing 777 airplane flying New York to San Francisco (3000 miles) consumes 11,000 gallons of jet fuel. If the plane is full with 300 passengers, then how much energy (in Btu and kWh units) is used for this trip, per passenger? (Assume energy content of jet fuel is the same as that of gasoline.) Please show work.
