Question

A train was scheduled to reach the Mumbai Central railway station

1435 hours. It reached the station at 8:15 pm. How late was the train

Answer 1

5 hours and 40 minutes late

Explanation:

I am assuming by 1435 hours you meant 14:35 -- 2:35 pm.

Hence you subtract 8:15 by 2:35 as the two times you're subtracting should always be the same time format (12 or 24-hour) which is 12 hours in this case.

08:15

- 02:35

Since the minutes of the time above (:15) is higher than 35, we need to add 60 to 15 minutes and at the same time, reduce 8 hours by 1 hour to 7 hours since we are adding 60 minutes (1 hour) to :15:

07:75 (15+60)

- 02:35

and answer will be 5 hours and 40 minutes
