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 ?

The correct option is 29 hours 35 minutes.

To find the total travel time of the train, we can break down the journey day by day from departure to arrival.

Step 1: Calculate the travel time on May 30th, 2020
The train starts at 23:40 hours on May 30th.
Since a day ends at 24:00 hours, the time spent traveling on May 30th is:
24:00 hours - 23:40 hours = 20 minutes.

Step 2: Calculate the travel time on May 31st, 2020
May has 31 days, so May 31st is a full day of travel.
Travel time on May 31st = 24 hours.

Step 3: Calculate the travel time on June 1st, 2020
The train reaches Mumbai at 05:15 hours on June 1st.
Travel time on June 1st = 5 hours 15 minutes.

Step 4: Add up the total travel time
Total time = (Time on May 30th) + (Time on May 31st) + (Time on June 1st)
Total time = 20 minutes + 24 hours + 5 hours 15 minutes

Adding the hours and minutes separately:
Hours = 24 hours + 5 hours = 29 hours
Minutes = 20 minutes + 15 minutes = 35 minutes

Therefore, the total travel time of the train is 29 hours 35 minutes.
