Question 9
A truck requires 108 litres of diesel for covering a distance of 594 km. How much diesel will be required by the truck to cover a distance of 1650 km?
Diesel required by truck to travel 594 km = 108 litres
Applying unitary method, where firstly we find the value of one unit and then the value of required number of units.
∴ Diesel required by truck to travel 1 km = 108594 = 211 litres
∴ For covering 1650 km, diesel required by truck
= 211×1650 litres = 300 litres
Thus, 300 litres of diesel is required by truck to cover the distance of 1650 km.
