You must add on to 9:40. So what I did was 9 + 5 = 14. 14 - 12 = 2. So far it's 2:40. 25 minutes + 40. = 65. Well there are 60 minutes in an hours. So 65 would be equal to 1H and 5min. Now take that 1 hour. Add it to 2. 3 hours. And take your 5 minutes. There! 3:05
Departure 9:40; flight duration 5:25 (all are hours: minutes) Add up: 9:40 5:25 ------ 14:65 14 hours and 65 minutes, but 65 minutes = 1 hour + 5 minutes, so the arrival time is 15 hours and 5 minutes which is equal to 3 h and 5 min PM
