masya89 [10]

Answer:

132 kilometers

Step-by-step explanation:

Given: Pamela drove her car 99 kilometers and used 9 liters of fuel.

To find: Number of kilometers Pamela drove in 12 liters of fuel.

Solution:

It is given that Pamela drove her car 99 kilometers and used 9 liters of fuel. Also the relationship between kilometers and fuel is proportional.

So, let us assume that she can travel x kilometers in 12 liters of fuel.

By proportionality we have,

99:9 :: x:12

\frac{99}{9} =\frac{x}{12}

11=\frac{x}{12}

x=12\times11

x=132

Hence, she can travel 132 kilometers in 12 liters of petrol.
