Jane's goal is to exercise 1 hour a day, 5 days a week.  If she hits her goal weekly for 8 weeks, how many hours has Jane exercised?
Her goal is 1 hour a day for 5 days so on a weekly basis, she exercises 1*5 = <<1*5=5>>5 hours
If she works 5 hours a week for 8 weeks then she exercises 5*8 = <<5*8=40>>40 hours in 8 weeks
