To find out how much petrol is required for a journey of 500km, we first need to calculate the petrol consumption rate of the car.
Given that the car uses 2 litres of petrol for every 10km, we can set up a proportion:
2 litres / 10km = x litres / 500km
Now, we can cross multiply to solve for x:
10 * x = 2 * 500
10x = 1000
x = 100
Therefore, the car would require 100 litres of petrol for a journey of 500km.
A car uses 2 litres of petrol for every 10km it travels. Find how much petrol it requires for a journey of 500km
