N turtles are positioned symmetrically on the edge of a circumference with radius R. In a given moment every turtle goes with speed v towards the one before it, it towards the one before it and so on. After how much time will the turtles meet? The problem isn't hard, but for its entire solution it is better to find the law for movement of every turtle first. And after that find the equation of the trajectory of every turtle.
