Fuel efficiency is a critical aspect of vehicle operation, impacting both cost and environmental footprint. It refers to the distance a vehicle can travel per unit of fuel consumed, typically measured in kilometers per liter (km/L) or miles per gallon (mpg). In our case, the car achieves 12 km/L, meaning it can travel 12 kilometers on one liter of fuel. Understanding this metric is essential for calculating fuel needs for any given trip. Several factors influence fuel efficiency, including vehicle type, driving habits, and road conditions. Smaller, more aerodynamic vehicles generally offer better fuel efficiency than larger, heavier ones. Aggressive driving, such as rapid acceleration and braking, can significantly reduce fuel efficiency. Similarly, driving in stop-and-go traffic or on hilly terrain can increase fuel consumption. Regular maintenance, such as keeping tires properly inflated and ensuring the engine is in good condition, can also contribute to improved fuel efficiency. By understanding these factors, drivers can make informed decisions to optimize their fuel consumption and reduce costs.

Our primary question is: If a car travels 12 kilometers per liter of fuel, how many liters are needed to cover a distance of 240 kilometers? This is a classic problem of proportional reasoning, where we relate the distance traveled to the fuel consumed. To solve this, we need to determine the relationship between the distance and the fuel and then apply that relationship to the given distance of 240 kilometers. This problem is not only a mathematical exercise but also a practical scenario encountered by drivers planning trips. Accurately calculating fuel needs helps in budgeting for travel expenses and ensuring that you have enough fuel to reach your destination. The problem can be approached using different methods, such as setting up a proportion or using a simple division. We will explore the most straightforward method to provide a clear and concise solution. Understanding this type of problem can also help in making informed decisions about vehicle choice and driving habits to optimize fuel consumption.

To determine the amount of fuel needed for a 240 km trip, given that the car travels 12 km per liter, we use a simple division. The formula is: Total Liters Needed = Total Distance / Distance per Liter. In this case, the total distance is 240 km, and the distance per liter is 12 km. So, we divide 240 by 12 to find the total liters needed. 240 km / 12 km/L = 20 liters. Therefore, 20 liters of fuel are required to travel 240 km. This calculation demonstrates a direct proportionality: the greater the distance, the more fuel is needed. Understanding this relationship is crucial for real-world applications, such as trip planning and fuel budgeting. This straightforward calculation provides a clear and concise answer, making it easy to understand and apply in similar scenarios. The simplicity of the solution highlights the importance of basic mathematical skills in everyday situations. This type of calculation is not only useful for drivers but also for anyone involved in logistics, transportation, or travel planning.

To ensure clarity, let's break down the calculation step-by-step:

  1. Identify the given values: The car travels 12 kilometers per liter (km/L), and the total distance to be covered is 240 kilometers.
  2. Set up the formula: Total Liters Needed = Total Distance / Distance per Liter.
  3. Plug in the values: Total Liters Needed = 240 km / 12 km/L.
  4. Perform the division: 240 / 12 = 20.
  5. State the answer: Therefore, 20 liters of fuel are needed to travel 240 kilometers.

This step-by-step approach makes the calculation easy to follow and understand. Each step is clearly defined, allowing for a systematic solution to the problem. This method can be applied to similar problems involving fuel efficiency and distance calculations. Breaking down the problem into smaller steps also helps in avoiding errors and ensuring accuracy. This detailed approach not only provides the answer but also reinforces the understanding of the underlying mathematical principles. By following these steps, anyone can confidently calculate fuel needs for their trips, making it a valuable skill for drivers and travelers alike.

The question provides several answer options, and it's essential to identify the correct one based on our calculation. The options are:
