Solution
On the basis of given table, the distance travelled by one of the new eco-friendly energy-efficient earns travelled on gas.
The car travelled 15 km in 1 L of gas.
The car travelled 7.5 km in 0.5 L of gas.
The car travelled 30 km in 2 L of gas.
This rate shows direct proportion between litres of gas and the distance cover.
The car can cover the distance in 8 L of gas = 8 × 15 = 120 km
