Do they cross each other again?<br/><br/>I remember doing these types of questions for Math... (what the hell, why did we need to do these types of questions for Math class????!!!!)<br/><br/>But now I've totally and seriously forgotten the answer... <br/><br/>Talking about time, by the way, it's 2:44am now... <br/>

<p>1-2 count once</p><p>2-3 count twice</p><p>3-4 count the third</p><p>and so on, no need to know the exact time when they match</p>
