A train left at 22:47 and arrived at its destination the next morning at 06:33. How long did the journey take?

Hint: The train left the station at 22:47 and reached the destination at 06:33. Here, we have to calculate the time taken by the train to complete the journey. For that, we will first calculate the duration between the times 22:47 and 24:00 and then we will calculate the duration between the times 00:00 and 06:33. Then we will add the both the time duration to get the required time taken by the train to complete its journey.

Complete step by step solution:
It is given that the train left the station at 22:47 and reached the destination at 06:33.
And we have to calculate the time taken by the train to reach its destination.
For that, we will first calculate the duration between the times 22:47 and 24:00
We have taken starting time to be 22:47 and end time to be 24:00
We will subtract both to get the duration.
As the end minutes are greater than the starting minutes, so we will add 60 to the minutes of the starting time and we will subtract 1 hour from end time hours.
Thus, the calculation becomes.
${\text{ }}23:60 - 22:47 = 01:13$
Now, we will first calculate the duration between the times 00:00 and 06:33
We have taken starting time to be 00:00 and end time to be 06:33
We will subtract both to get the duration.
Thus, the calculation becomes.
${\text{ 06:33 - 00:00 = 06:33}}$
Now, we will add both time durations to get the required time taken by the train to complete its journey.
Total time of journey $ = 01:13 + 06:33 = 07:46$
This is the required answer we needed.

Note: To find the duration between the two times, we will take one as starting time and the other as end time. We will find the difference to get the duration between the two times, but if the end minutes are smaller than the start minutes, we will add 60 minutes to the minutes and subtract 1 hour from the end time hours.
