    Since you are new, I want to give some advice about the site: **To get the best possible answers, you should explain what your thoughts on the problem are so far**. That way, people won't tell you things you already know, and they can write answers at an appropriate level; also, people are much more willing to help you if you show that you've tried the problem yourself.2012-07-25

    Do you have any thoughts on the problem? Have you found any points where they can meet? If you know one time when they meet, can you find another time when they meet? I added the alg-precalc tag.2012-07-25

    So, are these runners running forever? Is that what you mean by "keep running"?2012-07-25
