Question

lilys car has a fuel efficiency of 8 liters per 100 kilometers. what is the fuel efficiency of lilys car in kilometers per liter? \\(\square\frac{\text{km}}{\text{l}}\\) show calculator related content intro to dimensional analysis

Explanation:

Step1: Understand the conversion

We know the fuel efficiency is 8 liters for 100 kilometers. We need to find kilometers per liter, so we can think of it as how many kilometers are covered per 1 liter of fuel.
If 8 liters allow us to travel 100 kilometers, then for 1 liter, the distance (in kilometers) would be the total kilometers divided by the total liters. So the formula is $\frac{100\ \text{km}}{8\ \text{L}}$.

Step2: Perform the division

Calculate $\frac{100}{8}$.
$\frac{100}{8} = 12.5$

Answer:

12.5
