A flight is supposed to 1025 hours and reach its destination at 1320 hours. If it start 15 minutes late and arrives 19 minutes late,how longdoes it take to reach its destination?
Actual departure = 10:25 + 0:15 = 10:40
actual arrival = 13:20 - 0:09 = 13:11
actual time of flight = 13:11 - 10:40
= 12:71 - 10:40 = 2:31
