Calculation:
Departure time of train is 23 : 55 on 29th June.
Now, let's count the time duration,
On 30 June, till 23 : 55, 24 hours
On 1 July, till 23 : 55, 24 + 24 = 48 hours
On 2 July, till 5 : 20, (48 + 5 = 53 hours) and (20 + 5 = 25 minutes)
Hence, the time duration is 53 hours and 25 minutes.
