Question

3. a. (i) You are traveling on a plane trip from Washington, D.C. to Cleveland, Ohio andthe plane uses 1,260 MJ/passenger trip. If you made the trip by car it would take 18 gallons/passenger trip.There are 142 MJ in a gallon of kerosene, a type of jet fuel. How many gallons of kerosene does it take to make the trip by plane

Answer 1

#_galon = 8,873 gallons

Step-by-step explanation:

For this exercise let's use a direct rule of proportions (rule of three). If 1 gallon is 142 MJ, how many gallons is 1260 MJ

#_galon = 1260 MJ (1 gallon / 142 MJ)

#_galon = 8,873 gallons

therefore air travel uses less fuel than car travel
