Question

A car travels 432 km on 48 litres of petrol. Find the amount of petrol required to travel 180 km.

• A. 70
• B. 20
• C. 80
• D. 45

Answer 1

The correct option is B 20

Given, the car travels 432 km with 48 litres of petrol.

Hence, amount of petrol required to travel 1 km = $\frac{48}{432}$ = $\frac{1}{9}$ litres

Hence, amount of petrol consumed to travel 180 km = 180 x $\frac{1}{9}$ = $\frac{180}{9}$ = 20 litres
