calculate how long its from 15h07 to 18h38

To calculate the time difference between 15h07 and 18h38, we can follow these steps:

1. Convert both times to minutes:
- 15h07 = (15 * 60) + 7 = 907 minutes
- 18h38 = (18 * 60) + 38 = 1118 minutes

2. Find the difference between the two times:
1118 minutes - 907 minutes = 211 minutes

3. Convert the minutes back to hours and minutes:
211 minutes = 3 hours and 31 minutes

Therefore, it is 3 hours and 31 minutes from 15h07 to 18h38.

To calculate the duration between 15:07 and 18:38, follow these steps:

Step 1: Subtract the minutes of the starting time from the minutes of the ending time.
- 38 minutes - 7 minutes = 31 minutes

Step 2: Subtract the hours of the starting time from the hours of the ending time, while carrying over any extra minutes.
- 18 hours - 15 hours = 3 hours

Step 3: Combine the results from step 2 and step 1.
- The duration is 3 hours and 31 minutes.

Therefore, the duration from 15:07 to 18:38 is 3 hours and 31 minutes.
