A car covers 12.55 km of distance in 1 liter of petrol. How much distance will it cover in 36.75 liters of petrol?
Answer (1)
The car travels 12.55 km on 1 litre of petrol.
Multiply the distance covered per litre by the total litres of petrol: 12.55 × 36.75 .
Calculate the total distance: 461.2125 km.
The car will cover 461.2125 km.
Explanation
Understanding the Problem We are given that a car covers 12.55 km of distance in 1 litre of petrol. We need to find out how much distance the car will cover if it has 36.75 litres of petrol.
Setting up the Calculation The distance covered by the car is directly proportional to the amount of petrol it has. This means that if we multiply the amount of petrol by the distance covered per litre, we will find the total distance covered.
Calculating the Distance To find the distance the car covers with 36.75 litres of petrol, we multiply 12.55 km/litre by 36.75 litres: 12.55 × 36.75 = 461.2125
Final Answer Therefore, the car will cover 461.2125 km with 36.75 litres of petrol. We can round this to two decimal places, which is 461.21 km.
Examples
Imagine you're planning a road trip and need to estimate how much fuel you'll need. If you know your car's fuel efficiency (km per litre) and the total distance of your trip, you can calculate the amount of fuel required. For example, if your trip is 500 km and your car travels 12.55 km on 1 litre of petrol, you would need approximately 39.84 litres of petrol. This calculation helps you budget for fuel costs and plan your stops accordingly, ensuring a smooth and well-prepared journey.
