Calculating Monthly Fuel Usage for City Driving
As an excellent high school mathematics teacher, I'm excited to share a detailed explanation on how to calculate the monthly fuel usage of a car that averages 10.4 liters per 100 km of city driving and drives 1800 km per month in the city.
Understanding Fuel Efficiency
Fuel efficiency, or fuel economy, is a measure of how much fuel a vehicle consumes per unit of distance traveled. In this case, the car's fuel efficiency is 10.4 liters per 100 km of city driving. This means that for every 100 km of city driving, the car will use 10.4 liters of fuel.
Calculating Monthly Fuel Usage
To calculate the monthly fuel usage, we need to first convert the fuel efficiency from liters per 100 km to liters per km. We can do this by dividing 10.4 by 100, which gives us 0.104 liters per km.
Now, we can multiply the fuel efficiency (0.104 liters per km) by the monthly city driving distance (1800 km) to get the total monthly fuel usage:
- Fuel Efficiency: 0.104 liters per km
- Monthly City Driving Distance: 1800 km
- Monthly Fuel Usage = 0.104 liters/km × 1800 km = 187.2 liters
Therefore, the car will use approximately 187.2 liters of fuel in an average month of city driving.
Importance of Fuel Efficiency
Knowing the monthly fuel usage is important for several reasons:
- Budgeting: This information can help drivers plan their transportation budget and anticipate fuel costs.
- Environmental Impact: Fuel-efficient vehicles have a lower environmental impact, as they consume less fuel and emit fewer greenhouse gases.
- Maintenance: Monitoring fuel usage can also help identify potential issues with the vehicle, such as a decrease in fuel efficiency, which may indicate the need for maintenance or repairs.
By understanding the fuel efficiency and monthly fuel usage of their vehicles, drivers can make informed decisions about their transportation choices and take steps to improve their fuel economy, save money, and reduce their environmental impact.
