Answer 2

To add the given durations, we need to add the minutes separately and the seconds separately.

Minutes: 20 minutes + 3 minutes = 23 minutes

Seconds: 35 seconds + 45 seconds = 80 seconds

Now, we need to convert the total seconds to minutes and seconds. Since there are 60 seconds in a minute, we divide the total seconds by 60 to get the minutes and take the remainder as the remaining seconds.

80 seconds ÷ 60 = 1 minute remainder 20 seconds

Adding the minutes and seconds separately, we have:

23 minutes + 1 minute = 24 minutes 20 seconds

Therefore, 20 minutes 35 seconds + 3 minutes 45 seconds = 24 minutes 20 seconds.
