Answer: Joanne works 330 hours in a 5-week period.
Step-by-step explanation: First let's find out how many hours a week Joanne works. We know she works 11 hours a day and 6 days a week, so we multiply 11 and 6. 11*6=66.
So 66 hours a week. Now we multiply 66 by 5 to find out how many hours she works in 5 weeks. We know how much she works per week, so we multiply 66 and 5. 66*5=330
