A rabbit is chasing a fox (hey, why not?). The fox is trotting in a straight line at a constant speed v while the rabbit is running at a speed u > v in such a way that its velocity is always directed toward the fox.

What is the distance covered by the rabbit by the time it catches up with the fox?
