Asked by Jason
Two skaters, one with mass 62 kg and the other with mass 45 kg, stand on an ice rink holding a pole of length 10 m and negligible mass. Starting from the ends of the pole, the skaters pull themselves along the pole until they meet. How far does the 45 kg skater move?

They meet at the center of mass, which does not move.
Measured from the original 45 kg skater location, the CM is 620/107 = 5.79 m away.
That is how far that skater moves.
