Steps to add minutes and seconds:
1. Add the minutes.
2. Add the seconds.
3. If the seconds are 60 or more, then, decrease the seconds by 60 and increase the minutes by 1.
(Since, 1 minute = 60 seconds)
For example: Let's add:
3 minutes 47 seconds + 2 minutes 23 seconds = ?
First let's add the minutes.
3 minutes + 2 minutes = 5 minutes
Now, add the seconds.
47 seconds + 23 seconds = 70 seconds
So, 3 minutes 47 seconds + 2 minutes 23 seconds = 5 minutes 70 seconds
Now, notice that 70 seconds are more than 60 seconds.
So, decrease the seconds by 60 and increase the minutes by 1:
70 seconds – 60 seconds = 10 seconds
5 minutes + 1 minute = 6 minutes
So, 3 minutes 47 seconds + 2 minutes 23 seconds = 6 minutes 10 seconds.
