Average hours a nurse instructor or educator puts in a week

What is the average hours you all work as a nursing instructor a week, and the average hours one works as a nurse educator for a hospital. Also what is the salary of a nurse instructor vs. nurse educator and if you get paid hourly what is that amount for a nurse instructor vs. nurse educator. I know nurse instructors work long hours but is it possible to be done with work by 5pm if you come to work a couple hours early? What d you guys do to get all your work done in a timely manner?
