Calculating Fuel Consumption for a Trip

In this article, we will explore the concept of fuel economy and how to calculate fuel consumption for a trip using the information provided by a car's trip computer. We will use the given fuel economy of 8.5 L per 100 km to calculate the fuel consumption for different distances.

Calculating Fuel Consumption for 120 km

To calculate the fuel consumption for 120 km, we need to use the given fuel economy of 8.5 L per 100 km. Since the fuel economy is given per 100 km, we need to multiply the fuel economy by the number of 100 km units in 120 km.

Let's break it down:

120 km ÷ 100 km = 1.2 (this is the number of 100 km units in 120 km)
Fuel economy per 100 km = 8.5 L
Fuel consumption for 120 km = 8.5 L × 1.2 = 10.2 L

Therefore, the fuel consumption for 120 km would be approximately 10.2 L.

Calculating Fuel Consumption for 850 km

To calculate the fuel consumption for 850 km, we can use the same approach as before. We need to multiply the fuel economy by the number of 100 km units in 850 km.

Let's break it down:

850 km ÷ 100 km = 8.5 (this is the number of 100 km units in 850 km)
Fuel economy per 100 km = 8.5 L
Fuel consumption for 850 km = 8.5 L × 8.5 = 72.25 L

Therefore, the fuel consumption for 850 km would be approximately 72.25 L.

Calculating Distance Traveled with a Given Fuel Capacity

Now, let's say we have a car with a fuel capacity of 60 L, and we want to know how many kilometres we can travel with this fuel capacity. We can use the fuel economy of 8.5 L per 100 km to calculate the distance traveled.

Let's break it down:

Fuel capacity = 60 L
Fuel economy per 100 km = 8.5 L
Number of 100 km units that can be traveled = 60 L ÷ 8.5 L = 7.06 (round down to 7, since we can't travel a fraction of a 100 km unit)
Distance traveled = 7 × 100 km = 700 km

Therefore, with a fuel capacity of 60 L, we can travel approximately 700 km.

Conclusion

In this article, we have explored the concept of fuel economy and how to calculate fuel consumption for a trip using the information provided by a car's trip computer. We have used the given fuel economy of 8.5 L per 100 km to calculate the fuel consumption for different distances and the distance traveled with a given fuel capacity. By understanding these calculations, we can better plan our trips and make the most of our fuel capacity.

Key Takeaways

Fuel economy is given per 100 km unit.
To calculate fuel consumption for a trip, multiply the fuel economy by the number of 100 km units in the trip distance.
To calculate the distance traveled with a given fuel capacity, divide the fuel capacity by the fuel economy per 100 km unit and multiply by 100 km.

Real-World Applications

Understanding fuel economy and trip calculations can be useful in various real-world scenarios, such as:

Planning road trips and estimating fuel costs.
Optimizing fuel consumption for long-distance driving.
Calculating the fuel capacity required for a trip.
Making informed decisions about fuel-efficient vehicles.

Q: What is fuel economy, and how is it measured?

A: Fuel economy is the measure of how efficiently a vehicle uses fuel to travel a certain distance. It is typically measured in liters per 100 kilometers (L/100km) or miles per gallon (mpg). The fuel economy of a vehicle can vary depending on several factors, including the type of fuel used, the vehicle's weight, and the driving conditions.

Q: How do I calculate fuel consumption for a trip?

A: To calculate fuel consumption for a trip, you need to multiply the fuel economy by the number of 100 km units in the trip distance. For example, if the fuel economy is 8.5 L per 100 km and the trip distance is 120 km, you would multiply 8.5 L by 1.2 (120 km ÷ 100 km) to get 10.2 L.

Q: What is the difference between fuel economy and fuel efficiency?

A: Fuel economy and fuel efficiency are often used interchangeably, but they are not exactly the same thing. Fuel economy refers to the measure of how efficiently a vehicle uses fuel to travel a certain distance, while fuel efficiency refers to the ability of a vehicle to use less fuel to travel a certain distance. In other words, fuel economy is a measure of how well a vehicle uses fuel, while fuel efficiency is a measure of how well a vehicle can reduce fuel consumption.

Q: How can I improve my fuel economy?

A: There are several ways to improve your fuel economy, including:

Maintaining your vehicle regularly to ensure it is running at its best.
Driving at moderate speeds and avoiding rapid acceleration.
Removing extra weight from your vehicle.
Using the correct type of fuel for your vehicle.
Avoiding idling for extended periods of time.

Q: Can I calculate fuel consumption for a trip using a calculator?

A: Yes, you can use a calculator to calculate fuel consumption for a trip. Simply multiply the fuel economy by the number of 100 km units in the trip distance, and you will get the fuel consumption for the trip.

Q: What is the formula for calculating fuel consumption for a trip?

A: The formula for calculating fuel consumption for a trip is:

Fuel consumption = (Fuel economy × Trip distance) / 100

For example, if the fuel economy is 8.5 L per 100 km and the trip distance is 120 km, the fuel consumption would be:

Fuel consumption = (8.5 L × 120 km) / 100 = 10.2 L

Q: Can I use this formula to calculate fuel consumption for a trip in miles?

A: Yes, you can use this formula to calculate fuel consumption for a trip in miles. Simply convert the trip distance from kilometers to miles and use the formula as usual.

Q: What are some real-world applications of fuel economy and trip calculations?

A: Some real-world applications of fuel economy and trip calculations include:

Planning road trips and estimating fuel costs.
Optimizing fuel consumption for long-distance driving.
Calculating the fuel capacity required for a trip.
Making informed decisions about fuel-efficient vehicles.

By understanding fuel economy and trip calculations, you can make the most of your fuel capacity and reduce your fuel consumption, ultimately saving money and reducing your environmental impact.
