A) What should she except the car's average gas mileage to be in kilometers per liter?
B) During the year there, she drove 6000km. Assuming that gas costs $5/gal in europe, How much did she spend on fuel? (compute to the nearest dollar.)

1 mile = 1.6 km, so 1.6 km / 1 mile = 1
1 gallon = 3.785 liters, so 1 gal / 3.785 l = 1
So multiply your mpg by (1.6 km / mile) * (1 gal / 3.785 l)
Cancel the miles. Cancel the gallons. Calculate your answer in km per liter.
B)
Convert 6000km to miles using the relation above.
Convert miles to gallons using the car's mpg.
Convert gallons to cost using the cost of gas.

A..25 miles = 40 km
1 gallon US = 3.8 litres
40 km/gal ÷ 3.8 litres/gal. = 10.53km/litre
B..6,000 km ÷ 40 gal/km = 150 gal
= 150gal x $5.00/gal = $750 for gas.

You have a string of questions on the same subject matter. This suggests you do not understand equations of motion and you need your homework done.
You cannot learn unless you master the material and do your own homework.
You cannot use Yahoo! Answers on your in class exams.
I suggest you study the material
