Jane runs from 14h15 until 16h45. How long did he run

Jane ran for 2 hours and 30 minutes.

To calculate the duration of Jane's run, you need to subtract the starting time from the ending time.

The starting time is 14:15, and the ending time is 16:45.

To calculate the duration, let's break it down step by step:

1. Convert both the starting and ending times to minutes.
Starting time: 14:15 = (14 * 60) + 15 = 855 minutes
Ending time: 16:45 = (16 * 60) + 45 = 1005 minutes

2. Subtract the starting time from the ending time:
Duration = Ending time - Starting time
Duration = 1005 minutes - 855 minutes
Duration = 150 minutes

Therefore, Jane ran for 150 minutes.
