How do you add 2 hours and 45 minutes to 1 hour?

To add 2 hours and 45 minutes to 1 hour, you get 3 hours and 45 minutes.

When adding time, it's helpful to break it down into hours and minutes separately. Start by adding the hours together. In this case, you have 1 hour and 2 hours. Adding these gives you 3 hours.

Next, add the minutes. You have 45 minutes to add. Since there are no additional minutes in the initial 1 hour, you simply add the 45 minutes to the total. So, you now have 3 hours and 45 minutes.

If the minutes had added up to 60 or more, you would need to convert some of those minutes into hours. For example, if you had 1 hour and 30 minutes plus 2 hours and 45 minutes, you would first add the hours (1 + 2 = 3 hours) and then the minutes (30 + 45 = 75 minutes). Since 75 minutes is more than 60, you would convert 60 of those minutes into 1 hour, leaving you with 4 hours and 15 minutes.

In this simpler case, however, you don't need to convert any minutes into hours because 45 minutes is less than 60. So, the final answer remains 3 hours and 45 minutes.
