Final answer:
11:20 pm in 24-hour clock format is 23:20. PM times are converted to 24-hour format by adding 12 to the hour.
Explanation:
If it is 11:20 pm, the time in 24-hour clock format is 23:20. The conversion from 12-hour clock format to 24-hour format is straightforward for PM times: you add 12 to the PM time to get the equivalent 24-hour format. Since PM times represent the hours after noon, by adding 12 we ensure the count continues beyond 12:00, the starting point of the PM cycle in a 12-hour clock system.
