Answer 2

To calculate the duration between 20 hours 15 minutes and 19 hours 35 minutes, you need to subtract the starting time from the ending time. Keep in mind that if the ending time is earlier than the starting time, you might need to borrow an hour.

Let's perform the calculation:

Ending time: 19 hours 35 minutes Starting time: 20 hours 15 minutes

Step 1: Convert 19 hours 35 minutes to hours and minutes: 19 hours 35 minutes = 19 hours + 35 minutes

Step 2: Subtract the starting time from the ending time:

19 hours 35 minutes - 20 hours 15 minutes

Subtract the minutes first: 35 minutes - 15 minutes = 20 minutes

Now, since the ending time (19 hours 35 minutes) is earlier than the starting time (20 hours 15 minutes), we need to borrow an hour from the 19 hours and add it to the minutes:

19 hours - 1 hour = 18 hours

Step 3: Combine the results:

Duration = 18 hours 20 minutes

So, the duration between 20 hours 15 minutes and 19 hours 35 minutes is 18 hours and 20 minutes.
