Problem of the Month

Boeing 747

According to Boeing's Web site, the 747 burns approximately 5 gallons of fuel per mile.

A Boeing 747 can take a maximum of around 50,000 gallons of fuel, and a Boeing 747 will pay around $140,000 USD for a full fuel tank.

A 747 cruises at 500 mph.

The total distance from Washington, DC to Denver, CO is 1,493 miles.

How much does jet fuel cost (per gallon)?

How much would the fuel cost for a trip from Denver to DC?

How many miles per gallon would the 747 get on a trip from Denver to DC?

How long would the trip from Denver to DC take?

Solution to the Problem:

Since it costs $140,000 for 50,000 gallons of fuel, jet fuel costs $2.80 per gallon.

The 747 would burn 7,465 gallons of fuel from Denver to DC and would cost $20,902.

It would get .2 mpg over the trip and would take approximately 3 hours (2.986 hours).
