Question

Guo Qi watches 15 videos on Khan Academy every day. Each video is 8 minutes long on average. For how many days does Guo Qi need to watch videos on Khan Academy to watch 9000 minutes of videos?

Answer 1

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.

Answer 2

15x8= 120 minutes a day

9000/120 = 75 days he needs to watch
