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.
