## Task 1 - 110611

Two cars of the "Wartburg" type covered one a distance of $1200 \mathrm{~km}$, the other a distance of $800 \mathrm{~km}$. It is assumed that each of the two cars consumed the same amount of fuel per kilometer. The second car consumed 36 liters less fuel than the first.

Calculate how many liters of fuel both cars together consumed for the distances mentioned above!
Due to $1200-800=400$, the first car traveled $400 \mathrm{~km}$ more than the second. For these $400 \mathrm{~km}$, it consumed 36 liters of fuel according to the problem.

Both cars together traveled $1200 \mathrm{~km}+800 \mathrm{~km}=2000 \mathrm{~km}$. This is 5 times as much as $400 \mathrm{~km}$. Consequently, they consumed a total of $5 \cdot 36=180$ liters of fuel for these distances.
