Question

A car covers 110 km using 5 litres of petrol. How much distance will it cover using 15 litres of petrol?

Answer 1

The car covers 110 km using 5 liters of petrol.

Hence, using one liter, the car covers 110/5 = 22 km of petrol.

Therefore, with 15 liters of petrol, the distance the car covers = 22 * 15 = 330 km of petrol.

Answer 2

Solution :-

This question can be solved through the Unitary Method.

In 5 litres of petrol the car covers distance = 110 km

In 1 litre of petrol the car will cover distance = 110/5 km

In 15 litres of petrol the car will cover distance = (110*15)/5 km

= 1650/5 km

= 330 km

So, the car will cover 330 km in 15 litres of petrol.
