Counting forward, there are 9 hours between 9:30 am and 6:30 pm.

Since you left at 6:05 pm, which is 25 minutes from 6:30 pm, subtract 25 minutes from 9 hours:

8 hours 35 minutes

You could also convert the time to 24-hour time (18:05 instead of 6:50 pm) and change it from hours and minutes to just hours:

9:30 am → 9 + 1/2

6:05 pm → 18 + 1/12

and subtract the two, then convert back into hours and minutes
