Two persons of masses $\displaystyle 55$ kg and $\displaystyle 65$ kg respectively, are at the opposite ends of a boat. The length of the boat is $\displaystyle 3.0$ m and weighs $\displaystyle 100$ kg. The $\displaystyle 55$ kg man walks up to the $\displaystyle 65$ kg man and sits with him. If the boat is in still water the center of mass of the system shifts by :
