Question Video: Finding the Rate of Fuel Consumption of a Car Mathematics • 6th Grade

Video Transcript

A car uses 10 liters of fuel to travel 50 kilometers. What is the car’s fuel consumption rate in liters per kilometer?

We are told in the question the car uses 10 liters of fuel and travels 50 kilometers. As the fuel consumption rate is measured in liters per kilometer, we need to calculate the number of liters of fuel required to travel one kilometer. When dealing with equivalent fractions, we must multiply or divide the numerator and denominator by the same number.

In this case, 50 kilometers divided by 50 is equal to one kilometer. This means we need to divide the numerator by 50. 10 divided by 50 can be written as a fraction as shown. The top and bottom are divisible by 10. So this is equivalent to one-fifth. One-fifth is the same as the decimal 0.2. This means that the car will use 0.2 liters to travel one kilometer. The fuel consumption rate can be written as 0.2 liters per kilometer.
