This math topic focuses on calculating the elapsed time in a negative sense, where students find out how much earlier one time is compared to another. Specifically, problems present two times, and the task is to determine the difference in hours and minutes between them. The topic is part of a broader unit on handling negative elapsed times. Each question provides multiple-choice answers, requiring students to select the correct duration that one time occurs earlier than another.
