What is the total duration of one complete EPU cycle (2 minutes on, 1 minute off)?

• A. 2 minutes
• B. 4 minutes
• C. 3 minutes
• D. 5 minutes

Answer: (C)

The total duration of a cycle is the sum of all its phases. If it runs 2 minutes on and 1 minute off, you add them: 2 + 1 = 3 minutes. That 3-minute span is the period of one complete cycle, after which it repeats. Seeing 2 minutes would only reflect the on time, while 4 or 5 minutes would imply more than one full cycle or a miscount.
