Answer 2

Hey,

Initial distance traveled = 432 km

Initial amount of petrol = 48 litre

So, we can use unitary method here.

For 48 litre of petrol , it travels 432 km

For 1 litre petrol , it will travel 432/48 km = 9 km

⇒ For 20 litre of petrol , it will travel 20×9 km = 180 km

∴The required answer is 180 km.
