السؤال 37

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

15 litres per km
294 km per litre
15 km per litre, found by dividing distance by fuel usedالإجابة الصحيحة
336 litres per km

الشرح

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.
