Time limits are specific periods set for completing a task or activity. They help ensure that projects are finished on schedule and can improve productivity by encouraging focus and efficiency. Time limits can be found in various contexts, such as school assignments, work deadlines, and sports competitions. In many cases, time limits are established to promote fairness and organization. For example, in exams, students must complete their answers within a designated timeframe. Similarly, in tournaments, teams must finish their games before a certain time to keep the event running smoothly.
