16. Given that military time uses a 24-hour clock (12:00 midnight equals to 24:00), what time is 1/3 of a day past 9:15 a.m. in military time?
Answer: A
17:15 hours
1/3 of a day past 9:15 a.m. translates to adding 8 hours and 20 minutes to the given time. When calculated, this brings us to 17:15 hours in military time.
A) 17:15 hours
This option is correct as it accurately represents the time calculated by adding 8 hours and 20 minutes to 9:15 a.m. Specifically, 9:15 a.m. plus 8 hours is 5:15 p.m., and adding an additional 20 minutes results in 17:15 hours.
B) 12:15 hours
This option is incorrect because adding 1/3 of a day, which is 8 hours and 20 minutes, to 9:15 a.m. does not result in 12:15 p.m. Instead, it underestimates the total time added.
C) 21:15 hours
This choice is also incorrect as it suggests a time of 9:15 p.m. Adding 8 hours and 20 minutes to 9:15 a.m. does not reach the evening hours but rather stays within the 5:15 p.m. timeframe.
D) 15:15 hours
This option is incorrect because it implies a time of 3:15 p.m. Adding 8 hours and 20 minutes to 9:15 a.m. exceeds this time significantly, leading to a later hour.
Conclusion
The correct answer of 17:15 hours is definitively right as it reflects the accurate calculation of adding 1/3 of a day to 9:15 a.m. All other options fail because they do not align with the proper addition of time, demonstrating a misunderstanding of the 24-hour clock system.
