Let's see how many minutes of videos he watches everyday.
15 * 8 = 120
If he watches 120 minutes of Khan Academy every day, divide 9000 by 120 to see how many days it will take for him to watch 9000 minutes in total.
9000 / 120 = 75
It will take Guo Qi 75 days to watch 9000 minutes of Khan Academy.
