    Find Number of Kilometers

    If a car travels 36 miles per gallon of fuel (in other words the car does 36 mpg), how many kilometers does it travel per liter of fuel?

    Hi RTC1996,

    \frac{36\:mi}{1\:gal} \approx \frac{36 \times 1.6\:km}{1 \times3.8 \:l}\approx \frac{56.6\:km}{3.8\: l} \approx 15.2\: km/l

    It is necessary to know about liter of fuel for cars or just conversion factors to answer such questions?

    Well, if the data is in miles and gallons and the answer has to be in kilometres and litres, what do you think ...?!

    What do you mean by "know about liter of fuel for cars"? There are many things one could know about "liters" or about "fuel" that are not necessary for this particular problem.
