Answer 2

Given,

A car consumes 12 litres of petrol to travel a distance of 144 km.

To Find,

How much petrol is required to cover 240 km​?

Solution,

We can solve the question as follows:

It is given that a car consumes 12 litres of petrol to travel a distance of 144 km. We have to find the amount of petrol required to cover 240 km.

$Litres\: of\: petrol\: consumed\: to\: travel\: 144\: km = 12\: litres$

Then, the litres of petrol required to travel 1 km will be:

$Litres\: of\: petrol\: consumed\: to\: travel\: 1\: km = \frac{12}{144}$

                                                                $= \frac{1}{12}\: litres$

Now, the amount of petrol required to cover 240 km will be:
$Litres\: of\: petrol\: required\: to\: travel\: 240\: km = \frac{1}{12}*240$

                                                                    $= 20\: litres$

Hence, 20 litres of petrol is required to cover 240 km​.
