Answer
8 hours.
Work Step by Step
First lets add all of the hours together and the minutes together separately.
Hours:
2+1+3=6 hours
Minutes:
55+25+40=120
So the time is 6 hours and 120 minutes. Now since there are 60 minutes in 1 hour, we can say that there is 120 minutes in 2 hours. So therefore we eliminate the 120 minutes and add 2 hours to the time.
So, the total time is 8 hours.
