A car uses 6,5 litres of petrol per 100 km. How much petrol will it use on a trip of 400 km?
Answer and explanation
Correct answer: A. 26 litres
- Step 1: The trip is 400/100 = 4 units of 100 km.
- Step 2: Petrol = 4 × 6,5 = 26,0 litres.
Answer
26 litres.
Why not the others: 2600 litres: the 'per 100 km' was ignored. 61,53846153846154 litres: the distance was divided by the consumption. 260 litres: the conversion used 10 instead of 100.
