a car uses 25 litres of petrol to travel 200 miles. how many litres of petrol will the car use to travel 450 miles?
25/200 = x/450
Cross multiply and solve for x.
200x = 11,250
x = 56.25

8 car uses litres of fuel to travel 96 miles.
To calculate the amount of petrol a car will use to travel a certain distance, we need to determine the car's fuel efficiency, also known as mileage or fuel consumption rate.
In this case, the car uses 25 litres of petrol to travel 200 miles. To find the car's average fuel consumption rate, we divide the total distance traveled by the amount of petrol used:
Fuel consumption rate = Distance traveled / Amount of petrol used
To calculate the fuel consumption rate per mile, we divide the total fuel consumption by the distance traveled:
Fuel consumption rate per mile = Amount of petrol used / Distance traveled
In this situation, the fuel consumption rate per mile is:
Fuel consumption per mile = 25 litres / 200 miles = 0.125 litre/mile
Now that we have the fuel consumption rate per mile, we can determine the amount of petrol needed to travel 450 miles.
Amount of petrol needed = Fuel consumption per mile * Distance traveled
Amount of petrol needed = 0.125 litre/mile * 450 miles
Amount of petrol needed = 56.25 litres
Thus, the car will require 56.25 litres of petrol to travel 450 miles.
