Detailed Solution

The distance covered by a CNG bus and the CNG consumption rate are in direct proportion.
We know that if two quantities

x

and

y

vary in the same way while maintaining a constant ratio between their respective values, then the two quantities are said to be in direct proportion.
i.e.

x y = k,

where k is a constant positive number.
In case of direct proportion, if

y 1, y 2

are the values of

y

corresponding to the values

x 1, x 2

x

respectively, then

x 1 y 1 = x 2 y 2

Let’s assume that the distance covered in 1 kg CNG used = 100 km.
Then the distance covered in 2 kg CNG used = 200 km.
The distance covered in 3 kg CNG used = 300 km.
As a result, the amount of CNG used rises as the distance travelled rises.
