Final answer:
To find the duration of the journey, subtract the departure time from the arrival time in 24-hour format.
Step-by-step explanation:
To find the duration of the journey, we need to calculate the number of hours between the departure time and the arrival time. The train left Delhi at 7:30 a.m. on Friday and arrived in Chennai on Sunday at 5:15 p.m.
To calculate the duration in hours, we subtract the departure time from the arrival time:
(Sunday 5:15 p.m.) - (Friday 7:30 a.m.)
We can convert the given times into a 24-hour format and do the calculation:
- Friday 7:30 a.m. = 07:30
- Sunday 5:15 p.m. = 17:15
Now we subtract these times:
17:15 - 07:30 = 9 hours and 45 minutes.
Therefore, the duration of the journey is 9 hours and 45 minutes.
