Pamela drove her car 99 kilometers and used 9 liters of fuel. she wants to know how many kilometers (k) she can drive with 12 liters of fuel. she assumes the relationship between kilometers and fuel is proportional. how many kilometers can pamela drive with 12 liters of fuel?

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,

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

132 km on 12 liters.

Step-by-step explanation:

Just set up the proportion.

99 km : 9 liters :: x : 12 liters. Change this to an equation.

99/ 9 = x/12                             Divide the left

11 = x / 12                                 Multiply both sides by 12

11 * 12 = x/12 *12                      Combine the left and cancel the right.

132 = x

She can drive 132 km on 12 liters.

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
