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 =
[tex]=\dfrac{\text{Total minutes}}{\text{Average length of video}}\\\\=\dfrac{9000}{8}=1125[/tex]
Guo Qi needs to watch 1125 videos.
Number of days required =
[tex]=\dfrac{\text{Total number of videos}}{\text{Videos watched in one day}}\\\\=\dfrac{1125}{15}=75[/tex]
Guo Qi requires 75 days to watch videos on Khan Academy.
