This math topic focuses on calculating the elapsed time between two clock times with an emphasis on negative time intervals, rounding to the nearest five minutes. It practices the skill of determining how many minutes earlier the time shown on one clock is compared to another clock. The objective is to solve problems by calculating the time difference and enhancing proficiency in dealing with elapsed time, especially in more challenging, advanced scenarios. The problems are presented in multiple-choice format, with each having a set of potential answers.
