Question 1206233
the bus departed at 20:45.
midnight on the same day is 24:00.
24:00 minus 20:45 = 3:15 = 3 hours and 15 minutes from 20:45 to midnight.
24:00 hours from the previous day is 00:00 hours from the next day.
10:33 minus 00:00 = 10:33 = 10 hours and 33 minutes.
total time traveling = 3 hours and 15 minutes plus 10 hours and 33 minutes = 13 hours and 48 minutes.
