Civilian To Military Time

Explanation
The given question provides a time in the format of "11:00pm" and asks for its representation in the 24-hour format. In the 24-hour format, "11:00pm" is represented as "2300".

Explanation
The given answer "0100" is the correct representation of the time "1:00am" in the 24-hour format. In this format, the hours are represented from 00 to 23, and the minutes are represented from 00 to 59. Since it is 1:00am, the hour is 01 and the minutes are 00, resulting in the answer "0100".

Explanation
The given answer, 1830, is the military time representation of 6:30pm. In military time, the hours are represented from 00 to 23, with 00 being midnight and 23 being 11pm. To convert from the 12-hour clock system to military time, you simply add 12 to the hours if it is in the afternoon or evening. In this case, 6:30pm is in the evening, so adding 12 to 6 gives us 18, and the minutes remain the same. Therefore, the military time representation of 6:30pm is 1830.

Explanation
The given answer, 2130, is the military time equivalent of 9:30pm. In military time, the hours are represented on a 24-hour clock, where 00:00 is midnight and 23:59 is 11:59pm. To convert from a 12-hour clock to military time, you simply add 12 to the hours if it is after noon. In this case, since 9:30pm is after noon, we add 12 to 9, resulting in 21. Therefore, 9:30pm is equivalent to 2130 in military time.

Explanation
The given answer "0600" is the correct representation of the time "6:00am" in a 24-hour format. In the 24-hour clock system, the hours range from 00 to 23, where 00 represents midnight and 12 represents noon. Since "6:00am" is in the morning, it can be represented as "06:00" in the 24-hour format. However, since the question specifically asks for the time in a 4-digit format, the correct answer is "0600".

Explanation
The given answer "0448" is the correct representation of the time "4:48 am" in a 24-hour format. The first two digits "04" represent the hour (4), while the last two digits "48" represent the minutes (48).
