Oct 13, 2025 by wbrum.org 102 views

Introduction

When planning a road trip, it's essential to consider the fuel consumption and cost of the journey. In this article, we will determine the number of liters required to travel 100 km and calculate the cost of a full tank if the fuel costs R26.34 per liter. We will also express the fuel consumption in the form of 1 liter: km.

Calculating Fuel Consumption

To calculate the fuel consumption, we need to know the distance we want to travel and the fuel efficiency of our vehicle. Let's assume we have a vehicle with a fuel efficiency of 10 km/liter. This means that for every liter of fuel, our vehicle can travel 10 km.

Formula:

Fuel Consumption (liters) = Distance (km) / Fuel Efficiency (km/liter)

Plugging in the values:

Distance (km) = 100 km Fuel Efficiency (km/liter) = 10 km/liter

Fuel Consumption (liters) = 100 km / 10 km/liter = 10 liters

Calculating the Cost of a Full Tank

Now that we know the fuel consumption for a 100 km road trip, we can calculate the cost of a full tank. Let's assume our vehicle has a fuel tank capacity of 60 liters.

Formula:

Cost of a Full Tank = Fuel Consumption (liters) x Fuel Price (R/liter)

Plugging in the values:

Fuel Consumption (liters) = 10 liters Fuel Price (R/liter) = R26.34 per liter

Cost of a Full Tank = 10 liters x R26.34 per liter = R263.40

Expressing Fuel Consumption in the Form of 1 Liter: km

To express the fuel consumption in the form of 1 liter: km, we can simply divide the distance by the fuel consumption.

Formula:

Fuel Consumption (1 liter: km) = Distance (km) / Fuel Consumption (liters)

Plugging in the values:

Distance (km) = 100 km Fuel Consumption (liters) = 10 liters

Fuel Consumption (1 liter: km) = 100 km / 10 liters = 10 km/liter

Conclusion

In this article, we determined the number of liters required to travel 100 km and calculated the cost of a full tank if the fuel costs R26.34 per liter. We also expressed the fuel consumption in the form of 1 liter: km. By understanding the fuel consumption and cost of our vehicle, we can plan our road trips more effectively and make informed decisions about our fuel usage.

Calculating Fuel Consumption for Different Distances

Let's calculate the fuel consumption for different distances using the same formula:

Distance (km)	Fuel Consumption (liters)
50 km	5 liters
75 km	7.5 liters
100 km	10 liters
125 km	12.5 liters
150 km	15 liters

Calculating the Cost of a Full Tank for Different Fuel Prices

Let's calculate the cost of a full tank for different fuel prices using the same formula:

Fuel Price (R/liter)	Cost of a Full Tank (R)
R20 per liter	R200
R25 per liter	R250
R26.34 per liter	R263.40
R30 per liter	R300
R35 per liter	R350

Conclusion

Q: What is the formula to calculate fuel consumption?

A: The formula to calculate fuel consumption is:

Fuel Consumption (liters) = Distance (km) / Fuel Efficiency (km/liter)

Q: How do I calculate the cost of a full tank?

A: To calculate the cost of a full tank, you need to multiply the fuel consumption by the fuel price.

Cost of a Full Tank = Fuel Consumption (liters) x Fuel Price (R/liter)

Q: What is the fuel efficiency of a typical vehicle?

A: The fuel efficiency of a typical vehicle can vary depending on the make and model. However, a common fuel efficiency for a passenger vehicle is around 10-15 km/liter.

Q: How do I express fuel consumption in the form of 1 liter: km?

A: To express fuel consumption in the form of 1 liter: km, you can simply divide the distance by the fuel consumption.

Fuel Consumption (1 liter: km) = Distance (km) / Fuel Consumption (liters)

Q: What are some factors that affect fuel consumption?

A: Some factors that affect fuel consumption include:

Vehicle weight and size
Engine size and type
Driving habits (e.g. speed, acceleration, braking)
Road conditions (e.g. hills, traffic, weather)
Maintenance of the vehicle (e.g. oil changes, tire pressure)

Q: How can I improve my fuel efficiency?

A: Here are some tips to improve your fuel efficiency:

Regularly check and maintain your vehicle's tire pressure
Drive at a moderate speed and avoid sudden acceleration and braking
Remove extra weight from your vehicle
Use the correct oil for your vehicle
Avoid idling for extended periods of time

Q: What are some common mistakes that can affect fuel consumption?

A: Some common mistakes that can affect fuel consumption include:

Not checking tire pressure regularly
Driving with a dirty air filter
Not using the correct oil for your vehicle
Driving with a faulty oxygen sensor
Not maintaining your vehicle's spark plugs

Q: How can I calculate the cost of fuel for a road trip?

A: To calculate the cost of fuel for a road trip, you need to multiply the total distance of the trip by the fuel consumption per liter and then multiply the result by the fuel price.

Cost of Fuel = Total Distance (km) x Fuel Consumption (liters) x Fuel Price (R/liter)

Q: What are some tools that can help me calculate fuel consumption and cost?

A: Some tools that can help you calculate fuel consumption and cost include:

Fuel consumption calculators online
Mobile apps that track fuel consumption and cost
Vehicle manufacturer's fuel efficiency estimates
Fuel price comparison websites

Conclusion

In this article, we answered some frequently asked questions about fuel consumption and cost. We covered topics such as calculating fuel consumption, expressing fuel consumption in the form of 1 liter: km, and improving fuel efficiency. We also discussed common mistakes that can affect fuel consumption and provided some tools that can help you calculate fuel consumption and cost.
