If a car travels 120km on 45 litres of petrol, how much petrol is needed for a journey of 600km?
Answer Details
To find out how much petrol is needed for a journey of 600 km, we need to use the given information about the car's fuel consumption. The car travels 120 km on 45 litres of petrol, so we can set up a proportion: 120 km / 45 litres = 600 km / x litres We can cross-multiply to solve for x: 120 km * x litres = 45 litres * 600 km x = (45 litres * 600 km) / 120 km x = 225 litres Therefore, the amount of petrol needed for a journey of 600 km is 225 litres. So the correct option is: 225 litres.
