Can anyone help me with this?

Constant of proportionality is

Equation is

================================================

Explanation:

The general equation they give is c = rg

Solving for r leads to . We divided both sides by g to get this.

Now pick any point on the diagonal line. I'll pick (3,10)

The graph shows the horizontal axis is g and the vertical axis is c. The point (3,10) means g = 3 and c = 10 pair up together.

Making r to be,

and the equation in the form c = rg would be

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

where r the answers
