Answer 2

Let's break down the calculations step by step:

1. 80 seconds multiplied by 2: 80 seconds * 2 = 160 seconds

2. 6 minutes 40 seconds divided by 5: Convert 6 minutes 40 seconds to seconds: 6 minutes * 60 seconds/minute + 40 seconds = 400 seconds Divide 400 seconds by 5 = 80 seconds

3. 3 minutes 46 seconds + 2 minutes: Convert 3 minutes 46 seconds to seconds: 3 minutes * 60 seconds/minute + 46 seconds = 226 seconds Convert 2 minutes to seconds: 2 minutes * 60 seconds/minute = 120 seconds Add the two: 226 seconds + 120 seconds = 346 seconds

So, the final result is: 160 seconds = 2 minutes 40 seconds 80 seconds 346 seconds = 5 minutes 46 seconds

Adding these together: 2 minutes 40 seconds + 5 minutes 46 seconds = 8 minutes 26 seconds.
