Tony and Debra walk around a track. Tony walks each lap in 

10

 minutes. Debra walks each lap in 

6

 minutes. The two of them begin at the starting line at the same time. They walk until they meet again at the starting line.

The least common multiply of 10 and 6 is 30.

 

So, in 30 minutes, they will meet at the starting point.

 

Tony will have walked 3 laps and Debra will have walked 5 laps.
