Example 5: The running time of a Vande Bharat train from New Delhi to Varanasi is 8 hours.
If the train departs from New Delhi station at 6:15 a.m., at what time will it reach Varanasi?

Solution: The train will reach Varanasi 8 hours later than 6:15 a.m.
So, we add 8 hours to 6:15 a.m.
6:15 a.m. = 06 hours 15 minutes

8 hours = + 08 hours 00 minutes
= 14 hours 15 minutes

14 hours 15 minutes = 2:15 p.m.

Thus, the train will reach Varanasi at 2:15 p.m.

Knowledge Desk

The Vande Bharat Train is the fastest train in India. The coaches of the train are fitted
with automatic sliding doors and all the coaches are interconnected. The first Vande
Bharat Train was flagged off on the New Delhi - Kanpur - Varanasi route on Feb 15, 2019.

Example 6: Mayank’s school starts at 7:30 a.m. and closes at 2:15 p.m.
Find the working hours of the school. school

Solution: Closing time of the school = 2:15 p.m.
= 1415 hours
Opening time of the school = 7:30 a.m. = 0730 hours h min

Working hours of the school = 1415 hours – 0730 hours 14 15
= 0645 hours – 7 30
= 6 hours 45 minutes 6 45
Thus, the working hours of the school is 6 hours 45 minutes.

Example 7: A train leaves Meerut station at 9:50 p.m. and reaches Kolkata at 5:30 a.m. the
next day. Find the duration of the journey. h min
Solution: Departure time of the train = 9:50 p.m. = 2150 hours 23 60
Time interval from 9:50 p.m. to 12 midnight 24 00
= 2400 hours – 2150 hours – 21 50

= 0210 hours
= 2 hours 10 minutes

Time interval from 12 midnight to 5:30 a.m., the next day
= 5 hours 30 minutes h min
So, total time taken = 2 h 10 min + 5 h 30 min 2 10

= 7 hours 40 minutes. + 5 30

Thus, the duration of journey is 7 hours 40 minutes.
