Question

pamela drove her car 99 km and used 9 L of fuel. she wants to know how many kilometers if you can drive with 12 L of fuel. she assumes the relationship between kilometers and fuel is proportional. how many kilometers can pamela drive with 12 liters of fuel?

Answer 1

Pamela can drive 132 kilometers.

Answer 2

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.
