  1. Where they "lap" each other the first time may or may not be the starting point (although it is here); so look for the time that is a integer multiple of both 6 minutes and 8 minutes. That would be 24 minutes, the least common multiple of 6 and 8. One person will have run 4 laps and the other 3.
