A car uses 2 litres of petrol for every 10km it travels. Find how much petrol it requires for a journey of 500km

Answer 1

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.
