They would meet 30 times after 10 minutes.
Since Nick and Sally run on the 100m straight track, Nicks's speed is 3m / s, Sally's speed is 2m / s, if they star from two sides of the track, running towards each other continuously, to determine how many times they would meet each other after 10 minutes the following calculation must be performed:
- 100 = 3 x 20 + 2 x 20 = 60 + 40
- 10 x 60 = 600
- 600/20 = 30
Therefore, they would meet 30 times after 10 minutes.
