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?
Let’s work this out in a step by step way to be sure we have the right answer.

Her goal is 1 hour a day for 5 days so on a weekly basis, she exercises 1 * 5 = 5 hours.

If she works 5 hours a week for 8 weeks then she exercises 5 * 8 = 40 hours in 8 weeks.
