 Circular Jogging Track Problem 2 (Posted on 2006-04-13)
Three friends A, B and C regularly jog in a circular jogging track every morning. The track is 1000 m in circumference.

A takes 8 mins to complete one lap, B takes 10 mins and 40 secs and C takes 12 mins. All of them setout from a same point but C runs in the opposite direction from starting point.

Another friend D joins this run. D normally takes 13 mins and 20 secs to complete one lap. He decides to run in the same direction as C but from a point 600 m ahead of C in his jogging direction. When will they all meet each other on the circular track & where?

There is nothing keeping the meeting point from being at the starting line.  That just happened to be the solution to both of salil's problems.

For example if A completed 4.5 laps in the time B completed 3.5 and C completed 2.5 they would all meet on the other side of the track.
