Final answer:
The 24-hour clock has three key advantages: it eliminates ambiguity between AM/PM, it is more universally used, particularly in scientific and military contexts, and it simplifies calculations of duration because it eliminates the need to consider AM and PM.
Step-by-step explanation:
There are several advantages of using a 24-hour clock as opposed to a 12-hour clock. First, the 24-hour clock avoids any ambiguity between AM and PM. For example, when someone says it's 2:00, it's unclear whether they mean 2:00 AM or 2:00 PM.
But with a 24-hour clock, 14:00 clearly means 2:00 PM, leaving no room for confusion. Second, a 24-hour clock is more commonly used globally, particularly in scientific and military contexts. This makes it a more universal method of timekeeping.
Lastly, the 24-hour clock makes calculating the duration of events or time periods easier because you don't have to consider AM and PM.
