Answer:
3 hours and 25 minutes
Explanation:
Since these times are both AM, you can just change the form to 8.35 and 5.50 and subtract.
8.35- 5.50 = 2.85
And since there are max of 60 minutes in an hour, you take the 60 minutes from the 85 minutes, and you're left with 3 hours and 25 minutes.
Hope this helped :D
