Question

A car travels 40 km with $2\frac{1}{2}$ litres of petrol. How much distance can it travel with 1 litre of petrol?

• A. 12 km
• B. 20 km
• C. 18 km
• D. 16 km

Answer 1

The correct option is D

16 km

Distance travelled by car = 40 km
Amount of petrol needed = $2\frac{1}{2}$ litres
Distance travelled in one litre of petrol $=40÷2\frac{1}{2}=40÷\frac{5}{2}=40\times \frac{2}{5}=16$ km
The car travels 16 km in 1 litre of petrol.
