Explanation:

This problem involves converting time expressions from a 12-hour format to a 24-hour format. The key concepts include understanding how to interpret phrases related to time and how to convert between the two formats.

Steps:

1. Quarter before noon:

• 12:00 PM – 15 minutes = 11:45 AM → 11:45

1. Half past midnight:

• 12:00 AM + 30 minutes = 12:30 AM → 00:30

1. 2 hours to 9:00 PM:

• 9:00 PM – 2 hours = 7:00 PM → 19:00

1. 3 hours and 2 minutes before 8:40 AM:

• 8:40 AM – 3 hours = 5:40 AM
• 5:40 AM – 2 minutes = 5:38 AM → 05:38

1. Half past 3 in the afternoon:

• 3:00 PM + 30 minutes = 3:30 PM → 15:30

1. 9 minutes to midnight:

• 12:00 AM – 9 minutes = 11:51 PM → 23:51

1. Quarter after 00:00 H:

• 12:00 AM + 15 minutes = 12:15 AM → 00:15

1. Quarter to 19:00 H:

• 19:00 – 15 minutes = 18:45 → 6:45 PM

1. Half past 13:00 H:

• 13:00 + 30 minutes = 13:30 → 1:30 PM

1. 5 to 23:00 H:

• 23:00 – 5 minutes = 22:55 → 10:55 PM

This method relies on understanding the basic principles of time calculation and conversion between 12-hour and 24-hour formats.
