Answer 2

To add the given time durations, we'll start by adding the hours separately and then the minutes separately. Let's go step by step:

1. Add hours: 12 hours + 4 hours = 16 hours (12 + 4 = 16) 13 hours + 16 hours = 29 hours (13 + 16 = 29)

2. Add minutes: 25 minutes + 45 minutes = 70 minutes (25 + 45 = 70) 27 minutes + 48 minutes = 75 minutes (27 + 48 = 75)

Now, we have 29 hours and 70 minutes for the first sum, and 29 hours and 75 minutes for the second sum. However, since 75 minutes is equivalent to 1 hour and 15 minutes (60 minutes + 15 minutes), we can further simplify the result:

1. For the first sum: 29 hours and 70 minutes becomes 30 hours and 10 minutes (29 hours + 1 hour = 30 hours, and 70 minutes - 60 minutes = 10 minutes).
2. For the second sum: 29 hours and 75 minutes becomes 30 hours and 15 minutes (29 hours + 1 hour = 30 hours, and 75 minutes - 60 minutes = 15 minutes).

So, the final results are:

12 hours 25 minutes + 4 hours 45 minutes = 17 hours 15 minutes 13 hours 27 minutes + 16 hours 48 minutes = 30 hours 15 minutes
