Question 3 Unitary Method Exercise 10.1

A car can cover a distance of 522 km on 36 liters of petrol. How far can it travel on 14 liters of petrol?

Answer:

Given that number of kilometres a car can cover by using 36 litres of petrol = 522 km Number of kilometres a car can cover by using 1 litre of petrol = 522/36

Hence, the number of kilometres a car can cover by using 14 litres = (522/36) × 14

= 203 km
