Final answer:
To find out how far the car would travel on 80 litres of petrol based on its fuel consumption rate, we set up a proportional relationship. Using the given data, the calculation shows that the car would travel 720 miles on 80 litres of petrol.
Step-by-step explanation:
The subject of this question is Mathematics and it involves a proportional relationship between the amount of petrol used and the distance travelled by a car. Since the car uses the same amount of petrol for each mile it travels, we can set up a proportion to find out how far the car would travel on 80 litres of petrol based on the given information that the car uses 55 litres to travel 495 miles.
Step-by-Step Calculation
Identify the known values: 55 litres for 495 miles.
Set up a proportion: (55 litres / 495 miles) = (80 litres / x miles), where x represents the unknown distance.
Solve for x: x = (80 litres * 495 miles) / 55 litres.
Calculate: x = (80 * 495) / 55.
Simplify: x = (39600) / 55.
Finish calculation: x = 720 miles.
Therefore, the car would travel 720 miles on 80 litres of petrol.
