The following table shows the distance travelled by one of the new eco-friendly energy-efficient cars travelled on gas.

Which type of properties are indicated by the table? How much distance will be covered by the car in 8 litres of gas?

On the basis of given table, the distance travelled by one new eco-friendly energy-efficient earns travelled on gas.

The car travelled 15 km in 1L of gas

The car travelled 7.5 km in 0.5L of gas

The car travelled 30 km in 2L of gas

This rate shows direct proportion between litres of gas and the distance cover.

The car can cover the distance in 8L of gas = 8× 15 = 120km
