A train starts from Patna on 30th May, 2020 at 23:40 hours and reaches Mumbai on 1st June, 2020 at 5:15 hours. What is the total travel time of train?

Calculate the time from 30 May 23:40 to 1 June 5:15. From 30 May 23:40 to 31 May 23:40 = 24 hours. From 31 May 23:40 to 1 June 5:15: from 23:40 to 24:00 = 20 minutes, then from 00:00 to 5:15 = 5 hours 15 minutes, total = 5 hours 35 minutes. Adding: 24 hours + 5 hours 35 minutes = 29 hours 35 minutes.
