Challenge: Relation between engine size and fuel consumption

Tâche

Swipe to start coding

From the audi_cars table calculate the average fuel consumption (mpg column) for each engine size (enginesize). Order results in descending order by the average value of mpg. Expected output: enginesize | average mpg.

Solution

The result may seem strange, but don't forget that the mpg column refers to miles per gallon. The greater this value, the less fuel car consumes.
