Answer:

Guo Qi requires 75 days to watch videos on Khan Academy.

Step-by-step explanation:

We are given the following in the question:

Number of videos watched by Guo Qi each day = 15

Average length of each video = 8 minutes

Total minutes of video = 9000 minutes

Total number of videos to be watched =

$=\dfrac{\text{Total minutes}}{\text{Average length of video}}\\\\=\dfrac{9000}{8}=1125$

Guo Qi needs to watch 1125 videos.

Number of days required =

$=\dfrac{\text{Total number of videos}}{\text{Videos watched in one day}}\\\\=\dfrac{1125}{15}=75$

Guo Qi requires 75 days to watch videos on Khan Academy.
