سؤال 37

A van travels 315 km using 21 litres of fuel. What is its distance per litre?

  1. 15 litres per km
  2. 294 km per litre
  3. 15 km per litre, found by dividing distance by fuel usedپاسخ درست
  4. 336 litres per km

توضیح

Distance per litre places distance over litres, so 315 divided by 21 gives 15 km per litre. Labeling the result as litres per km inverts the requested rate even if the division itself produced 15.
