You and your friends are organizing a trip to Europe. Your plan is to rent a car and drive through the major European capitals. By consulting a map you estimate that you will cover a total distance of 5000 km.
You select a rental package that includes a car with an average consumption of 6.0 liters of fuel per 100 km. In Europe the average fuel cost is 1.063 euros / liter.
How many gallons of fuel would the rental car consume per mile?
(Express your answer numerically in gallons per mile to three significant figures.)
1 km = 0.6214 mile
1 gallon = 3.785 liters

22.71 Gallons per 100km
50*100kms in 5000km
Total Fuel = 22.71×50=1135.5
To 3 Sig Figures = 1140
I think thats right

6.0 liters per 100 km
6.0 liters per 62.14 miles (if 1 km = 0.6214 mile then 100km = 62.14 mile by multiplying both by 100)
(Divide both by 62.14) 0.09655 liters per 1 mile
0.09655 divided by 3.785 (to convert from liters to gallons)
0.0255 gallons per mile.
