Answer :
The time 85 hours before 11 PM is 10 AM three days prior. This is discovered by dividing 85 by 24 to get 3 full days plus 13 hours, and subtracting that from the original time.
To calculate the time 85 hours before 11 PM, you first need to know that there are 24 hours in one day. Dividing 85 by 24 gives us 3 full days (72 hours) and an extra 13 hours. If we subtract 3 full days from the given time, it gets us to the same time of day 3 days before, which is 11 PM. Then, subtracting an additional 13 hours from 11 PM takes us to 10 AM (as there are 12 hours before 11 PM and 1 more hour to subtract).
Therefore, the time 85 hours before 11 PM will be 10 AM three days before. This problem required the understanding of the 24 hour day system and simple subtraction and division. Always remember to begin the subtraction from the end of a full day, that is 12 midnight when you need to count the hours before a certain time.
