You can put this solution on YOUR website! Two runners run around a circular track.
The first runner completes a lap in 7 minutes.
The second runner completes a lap in 13 minutes.
If they both start at the same place and the same time and go in the same direction, after how many minutes will they meet again at the starting place?
:
Find the least common multiple of 7 and 13, 7 * 13 = 91 minutes
At that time 1st runner will make exactly 13 laps, and 2nd runner makes 7 laps
