Final answer:
The subject is Social Studies, and the grade level is Middle School. The question is about the synchronization of time and provides examples and quotes for context. The answer explains how to convert thirteen hundred hours to the 12-hour clock and emphasizes the importance of agreement between individuals for time synchronization.
Step-by-step explanation:
The subject of this question is Social Studies and the grade level is Middle School.
The question is asking about the synchronization of time between two individuals. The student, Chad, states that his watch says thirteen hundred hours, mountain standard time. To determine if they are synchronized, it is important to convert the time to a more commonly used format, such as the 12-hour clock. Thirteen hundred hours is equivalent to 1:00 PM, so Chad's watch is indicating 1:00 PM mountain standard time. Whether they are synchronized or not depends on the agreement between them and their time zone settings.
It is important to note that the examples and quotes provided in the question are not directly related to the time synchronization inquiry, but rather serve as additional context or unrelated information.
