Which of the following is the correct 24-hour clock expression of 2.15p.m.?
Correct Answer
D. 14 15

The correct 24-hour clock expression for 2.15 p.m. is 14 15. In the 24-hour clock system, the hours range from 00 to 23, with 00 representing midnight and 12 representing noon. Since 2.15 p.m. is in the afternoon, it would be represented as 14 hours and 15 minutes in the 24-hour clock format.

In the 24-hour clock system, time is represented using four digits, with the first two digits representing the hour and the last two digits representing the minutes. In this system, 8:30 a.m. is written as 08:30, where 08 represents the hour and 30 represents the minutes. Therefore, the statement that 8:30 a.m. is written as 08 30 in the 24-hour clock is true.

09 06 h is also written as ___________
Correct Answer
09:06 a.m., 9:06 a.m., 9:06 am., 9:06 a.m, 09:06 am., 9:06 am
Explanation
The 24-hour clock notation 09 06 h is a way of telling time that uses a continuous count of 24 hours, starting at midnight (00 00 h). In this system, 09 06 h means it has been 9 hours and 6 minutes since midnight. The 12-hour clock notation, on the other hand, divides the day into two 12-hour periods: AM (ante meridiem) for the hours before noon, and PM (post meridiem) for the hours after noon. Therefore, 09 06 h, which falls within the AM period, is expressed as 9:06 AM in the 12-hour clock format.
8.
16 25h can also be written as _____________
Correct Answer
B. 4.25 p.m.
Explanation
The given time, 16 25h, can be written as 4.25 p.m. because in the 24-hour clock system, 16 represents 4 p.m. and 25 minutes past the hour is denoted as .25. Therefore, the correct representation of 16 25h is 4.25 p.m.
9.
10 p.m. is expressed as 22 00 on the 24-hour clock.
Correct Answer
