A vehicle covers a distance of 176.96 km in 14 litres of petrol. What is the average distance covered per litre?
Answer (1)
Divide the total distance covered by the total petrol consumed.
Substitute the given values: Total distance = 176.96 km, Total petrol = 14 litres.
Calculate the average distance: 14 176.96 = 12.64 .
The average distance covered per litre is 12.64 km/litre .
Explanation
Understanding the Problem We are given that a vehicle covers a distance of 176.96 km using 14 litres of petrol. We need to find the average distance covered per litre of petrol.
Setting up the Calculation To find the average distance covered per litre, we will divide the total distance covered by the total amount of petrol used. That is:
Average distance = Total petrol Total distance
Substituting the Values Now, we substitute the given values into the formula:
Average distance = 14 litres 176.96 km
Calculating the Result Performing the division, we find:
Average distance = 12.64 km/litre
Final Answer Therefore, the average distance covered per litre of petrol is 12.64 km/litre.
Examples
Imagine you're planning a road trip and want to estimate how much petrol you'll need. Knowing your vehicle's average distance per litre helps you calculate the total petrol required for the trip. For instance, if your trip is 500 km and your car averages 12.64 km/litre, you'll need approximately 12.64 500 ≈ 39.56 litres. This calculation ensures you can budget effectively for petrol expenses and avoid running out of fuel during your journey.
