Question 78
A car can travel 240km in 15 litres of petrol. How much distance will it travel in 25 litres of petrol?
Given, distance travelled by car in 15 litres = 240 km
Using unitary method in which first we find the value of one unit and then the value of the required number of units.
Distance travel by a car in 1 ;itre = 24015 = 16km
∴ Distance travel by a car in 25 litres = 16×25 = 400km.
Hence, the car will travel 400 km in 25 litres.
