0.03L/km

30km/L

0.04L/km

32km/1.2L

Answer 1

You want to compare km/L. The highest km/L represents the greatest efficiency. List that one first, then the others in descending order of km/L. Some of the given numbers are in L/km. You need to first find the reciprocal of those numbers to get km/L.
