6 hours and 25 min. You get this by dividing 60 by 4 to get 15 min for the 1 hour and 15 min. Then you multiply that by 3 for the three days to get 3 hours and 45 min. the you divide 60 by 3 to get 20 minutes and multiply 1 hr and 20 min by 2 for the 2 days. To get 2 hours and 40 minutes. Then you add the 3 hrs and 45 min with the 2 hrs and 40 min. To get 6 hours and 25 minutes.
