In a racecourse, horse A can run two laps in one minute, horse B can run three laps in one minute, and horse C can run four laps in one minute. May I ask: If these three horses start from the starting point at the same time, after a few minutes, they Meet at the starting point again?
在一个赛马场里，A马1分钟可以跑两圈，B马一分钟可以跑三圈，C马一分钟可以跑四圈，请问：如果这3匹马同时从起点出发，几分钟后，他们又相遇在起点上？
