Distance per litre20 km
Fuel price per litreGBP 2.00
What is the fuel cost of the journey in pounds?

Answer and explanation

Correct answer: C. GBP 40.00

  1. Step 1: Litres used = 400 / 20 = 20. Step 2. Cost = 20 x 2.00 = 40 pounds. Answer: GBP 40.00. Why not the others: GBP 800.00 multiplies the distance by the price without finding the litres used; GBP 22.00 adds the litres to the price, mixing units; GBP 10.00 divides the distance by (km per litre x price), which does not give a cost.
