Fifteen hours is equivalent to 3:00 PM if we consider it from a 12-hour clock format starting at midnight (00:00).
To explain further, the 24-hour clock format starts counting from midnight:
- 00:00 – 12:00 AM (midnight)
- 01:00 – 1:00 AM
- 12:00 – 12:00 PM (noon)
- And so on…
So, if we add 15 hours to 00:00:
- 12 hours brings us to 12:00 PM (noon).
- Adding 3 more hours (12:00 PM + 3:00) results in 3:00 PM.
Thus, 15 hours is equivalent to 3:00 PM.
