Answer 2

To add these two time durations together, you can add the hours, minutes, and seconds separately:

7 hours + 1 hour = 8 hours 23 minutes + 58 minutes = 81 minutes 57 seconds + 42 seconds = 99 seconds

Now, you need to carry over any excess minutes and seconds:

81 minutes = 1 hour and 21 minutes 99 seconds = 1 minute and 39 seconds

Now, add everything together:

8 hours + 1 hour (from carrying over) = 9 hours 1 hour (from carrying over) + 21 minutes = 22 minutes 1 minute (from carrying over) + 39 seconds = 40 seconds

So, 7 hours 23 minutes 57 seconds + 1 hour 58 minutes 42 seconds = 9 hours 22 minutes 40 seconds.
