Add 11 hours and 34 minutes to three hours and 43 minutes.
There are a few ways of answering this question. We will add the hours and minutes separately. 11 hours plus three hours is equal to 14 hours. 34 minutes plus 43 minutes is equal to 77 minutes. We know that 60 minutes is equal to one hour. The difference between 60 and 77 is 17. Therefore, 77 minutes is equal to one hour and 17 minutes.
We can now work out the total time by adding 14 hours to one hour and 17 minutes. This gives us a total time of 15 hours and 17 minutes.
