Answer 3

It looks like you're performing some calculations involving time. Let's break down the calculations step by step:

1. 13 hours 20 minutes + 2 hours 50 minutes:
   • Add the hours: 13 hours + 2 hours = 15 hours
   • Add the minutes: 20 minutes + 50 minutes = 70 minutes
   • Convert 70 minutes to hours and minutes: 70 minutes = 1 hour 10 minutes
   • Add the hours and minutes: 15 hours + 1 hour = 16 hours; 10 minutes

So, 13 hours 20 minutes + 2 hours 50 minutes = 16 hours 10 minutes.

2. 20 minutes 35 seconds + 3 minutes 45 seconds:
   • Add the minutes: 20 minutes + 3 minutes = 23 minutes
   • Add the seconds: 35 seconds + 45 seconds = 80 seconds
   • Convert 80 seconds to minutes and seconds: 80 seconds = 1 minute 20 seconds
   • Add the minutes and seconds: 23 minutes + 1 minute = 24 minutes; 20 seconds

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

I hope this helps! Let me know if you have any more calculations or questions.
