Point A moves uniformly with velocity v so that velocity v is continua

1.	Point A moves uniformly with velocity v so that velocity v is continually "aimed" at point B which in its turns moves rectilinearly and uniformly with velocity u lt v. At the initial moment of time v _\|_ u and the points are separated by a distance l. The time at which the two points will converge ( if v=2u ) is kl/3u.The value of 'k' is
