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 date by date from Patna to Mumbai:

Step 1: Time traveled on 30th May, 2020
The train starts at 23:40 hours on 30th May.
Since a full day ends at 24:00 hours (midnight), the time spent traveling on 30th May is:
24:00 hours - 23:40 hours = 0 hours 20 minutes.

Step 2: Time traveled on 31st May, 2020
May has 31 days. The train travels for the entire day of 31st May.
Time spent traveling on 31st May = 24 hours 00 minutes.

Step 3: Time traveled on 1st June, 2020
The train reaches Mumbai at 05:15 hours on 1st June.
Time spent traveling on 1st June = 5 hours 15 minutes.

Step 4: Calculate the total travel time
Adding up the travel duration across all three days:
Total time = 0 hours 20 minutes + 24 hours 00 minutes + 5 hours 15 minutes
Total hours = 0 + 24 + 5 = 29 hours
Total minutes = 20 + 0 + 15 = 35 minutes

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