Describe the difference between elapsed time and available time in a time-bound requirement.

• A. Elapsed time is the remaining time; available time is the actual time passed.
• B. Elapsed time is the actual time passed since start; available time is the remaining time to complete the action.
• C. Elapsed time and available time are the same.
• D. Available time is always zero.

Answer: (B)

When you have a time-bound requirement, you keep track of two time measures: how much time has already passed and how much time remains. Elapsed time is the actual time that has passed since the start of the task or window. Available time is the remaining time left to complete the action. For example, if you’re allowed 60 minutes and 15 minutes have elapsed, the elapsed time is 15 minutes and the available time is 45 minutes. This distinction is essential for monitoring progress and staying on schedule. The other statements mix up these meanings or assume they're the same, or that no time remains. Elapsed time isn’t remaining time, and available time isn’t the same as the time already passed. Available time isn’t always zero unless the deadline has just passed.
