1. The problem is to convert 12 minutes and 8 seconds into total seconds. 2. We know that 1 minute equals 60 seconds. 3. To find the total seconds, multiply the minutes by 60 and then add the remaining seconds. 4. Calculation: $$12 \times 60 + 8 = 720 + 8 = 728$$ seconds. 5. Therefore, 12 minutes and 8 seconds equals 728 seconds.
