Final answer:
The 24-hour clock prevents confusion between AM and PM times by using a time range from 00:00 to 23:59, which removes the need for additional designations and reduces ambiguity in communication.
Step-by-step explanation:
Using the 24-hour clock prevents confusion between AM and PM times. This system is especially useful for avoiding ambiguity in transport schedules, military operations, and in the medical field where precision is crucial. Unlike the 12-hour clock, which requires an additional designation of AM or PM to clarify the time of day, the 24-hour clock runs from 00:00 (midnight) to 23:59, making it clear whether the intended time is morning or evening.
The 24-hour clock is a way of telling time that dedates back to ancient Egypt but has been widely adopted in modern times for its accuracy and lack of ambiguity. It's particularly important in our globalized world where coordination across different time zones is essential, and in professions where precise timekeeping can be a matter of safety and efficiency.
