To find the time of the swimmer who came in second place, we need to sort the times from fastest to slowest. The times given are:
- 69.28 seconds
- 74.5 seconds

The order from fastest (lowest time) to slowest (highest time) is:
- 69.15 seconds (1st place)
- 69.28 seconds (2nd place)
- 74.5 seconds (3rd place)
- 75.4 seconds (4th place)
Thus, the time of the person who came in second place is 69.28 seconds.
