Answer 2

Given :

• In 5 litres of petrol a motorbike travells 225 km

To find :

• The distance the motorbike will cover in 1.5 litres of petrol

Solution :

Here we use the concept of Unitary Method. First we will find the distance the motorcycle can cover in 1 litre and then multiply our result with 1.5.

★ In 1 litre of petrol:-

→ Motorcycle can cover = (225/5) km

→ Motorcycle can cover = 45 km

★ In 1.5 litre of petrol:-

→ Motorcycle can cover = (45 × 1.5) km

→ Motorcycle can cover = 67.5 km

Answer :

• The motorcycle can cover 67.5 km in 1.5 litre of petrol.
