A car uses 8 litres of fuel to travel 100 km. How many litres does it need to travel 350 km at the same rate?
Answer and explanation
Correct answer: A. 28
- Step 1: The car uses 8 / 100 = 0.08 litres per km. Step 2. For 350 km: 350 x 0.08 = 28 litres. Answer: 28. Why not the others: 43.75 divides 350 by 8, and 2.8 and 280 put the decimal point in the wrong place.
