Solution

On the basis of given table, the distance travelled by one of the new eco-friendly energy efficient cars 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 km in 2 L of gas
This rate shows direct proportion between liters of gas and the distance cover. The car can cover the distance in 8 l of gas $= 8 \times 15 = 120$ km
