Two ships, 1 and 2, move with constant velocities 3 m/s and 4 m/s along two mutually perpendicular straight tracks toward the intersection point O. At the moment `t = 0`  the ships were located at the distances 120 m and 200 m from the point O. How soon will the distance between the ships become the shortest and what is it equal to ?
