To determine the time of the person who came in third place, we first need to sort the times in ascending order. The times are as follows:
- 68.92 seconds
- 69.15 seconds
- 72.3 seconds
- 73.2 seconds
Now we can arrange them from the fastest to the slowest:
- 68.92 seconds (1st place)
- 69.15 seconds (2nd place)
- 72.3 seconds (3rd place)
- 73.2 seconds (4th place)
Based on this order, the time of the person who came in third place is 72.3 seconds.
