She gave 1 60 minute session. You will take 7 and multiply times 60 and get 420. There are 420 min in 7 hours. Then you will take those 8 days of tutoring and multiply times those 420 minutes and get 3,360 minutes. You will then take that and divide by 60 and you get 56 so then you know you can not have another 60 minute session that week.
