## Task 4

A company has two cars of the type "Wartburg". One car drove 600 km in a week, and the other drove 900 km.

How many liters of gasoline did each car need, if the second car, which drove 900 km, used 27 liters more than the first?
The second car drives $300 \mathrm{~km}$ further and requires 27 liters for this. For $900 \mathrm{~km}$, this amounts to 81 liters. Thus, we have:

The first car consumed 54 l of gasoline. The second car consumed $81 \mathrm{l}$ of gasoline.
