Calculating Monthly Fuel Usage for City Driving
As a high school mathematics teacher, I often get questions from students about real-world applications of the concepts they learn in class. One such question that comes up frequently is how to calculate the monthly fuel usage of a car for city driving. In this article, I'll walk you through the step-by-step process to solve this problem.
Let's start with the given information:
- The car averages 10.4 liters of fuel per 100 km of city driving.
- The car averages 1800 km of city driving per month.
To calculate the monthly fuel usage, we need to follow these steps:
- Convert the fuel consumption rate to liters per kilometer:
- The car averages 10.4 liters per 100 km of city driving.
- To convert this to liters per kilometer, we divide 10.4 by 100:
- 10.4 liters / 100 km = 0.104 liters/km
- Calculate the total distance driven in the month:
- The car averages 1800 km of city driving per month.
- Multiply the fuel consumption rate by the total distance driven:
- Fuel consumption rate: 0.104 liters/km
- Total distance driven: 1800 km
- Monthly fuel usage: 0.104 liters/km × 1800 km = 187.2 liters
Therefore, the car uses approximately 187.2 liters of fuel in an average month of city driving.
It's important to note that this calculation assumes the car's fuel efficiency remains consistent throughout the month. In reality, factors such as driving conditions, weather, and the age of the vehicle can affect the actual fuel consumption. However, this method provides a good estimate of the monthly fuel usage based on the provided information.
By understanding how to perform these calculations, students can apply their mathematical knowledge to real-world situations and develop a better understanding of the factors that influence a car's fuel efficiency and monthly fuel usage.
