Question

Kolkata-Delhi train leaves Kolkata at 18:30 hours and travels the distance in 24 hours 25 minutes. At what time will the train reach Delhi?

Answer 1

Hint: We solve this problem by conversion of the time into minutes and then accordingly find the time, the Kolkata-Delhi train reaches Delhi. The conversion is given by 1 day = 24 hours.

Complete step by step solution:
We have,
1 day = 24 hours
Now, we know that the total duration of the travel is 24 hours 25 minutes. Thus, we should know that time comes back to the original time after 1 day (that is 24 hours). So, we can conclude that after 24 hours, we get back to 18:30 hours on the next day. Now, there are 25 minutes more remaining. We know that we can add 25 to 30, thus we get 30 + 25 = 55 minutes. Thus, the final time is 18:55 hours.
Hence, the Kolkata-Delhi train reaches Delhi at 18:55 hours (on the next day).

Note: To find the final time when total duration is given, we first start by adding the hour’s portion on the initial time and then proceed with the minutes. Example in this case, we first added 24 hours to the initial time of 18:30 hours and only then added the minutes. This technique greatly simplifies the approach to solve the problem.
