@dolari It's funny but still kinda needed --people don't necessarily know they're in the same order of magnitude, so as far as those people are concerned, it could've been "(some tens of kilometers)" or "(some hundreds of kilometers)", etc.
@dipolecat - I thought this ws rather silly, and if I was editing this to add miles/kilometers to this article, I would have just removed the reference and said "some distance" away. :)
