I'm on the English version, but my initial thought was also a typo, and what they meant was a way higher number. The problem is that the game doesn't really have a defined measure of a meter. You can only make assumptions.
In retrospect, I still believe it's partially a typo, but also partially a case of a misunderstanding between the guys defining the challenges and the programmers implementing them.
So we might simply have a broken challenge where the presented text is what the product owner wanted vs. what the programmer thought he wanted combined with rough deadlines.
