Problem P. 4074. (May 2008)

P. 4074. Two students run along a circular path. While Andy runs three laps, Bob runs four laps. While they are running both of them can see only the next one-third of the path. They start running at the same time at the same starting point and they also stop running at the same time and at same position. In what fraction of the running time can they see each other?
