You would need to start at 12:50 pm.
To solve this problem, you want to work backwards and find 4 hours and 10 minutes before 5:00 pm.
Well, to find 4 hours before 5:00 pm, subtract 4 from 5. you are left with 1:00 pm. Now, you need to find 10 minutes before that. To do this, you want 10 minutes before the turn of 1:00, so since the hour before 1 is 12, Your time would be 12:50, 10 minutes before 1:00.
I hope this helps and have a great rest of your day!
