Problem P. 4687. (December 2014)

P. 4687. There are two point-like masses at some distance from each other in the outer space. If one of them is fixed, then the other will hit it after a time of \(\displaystyle T_1=6\) minutes. In the reversed case, this time is \(\displaystyle T_2=8\) minutes. How much time elapses until the collision if both objects can move freely?
