Not working and nonexistent videos.
A few of the videos covering rates, and multiple rates, as well as the videos showing how to solve *rate problem 2* problems under intro to rates***
Please fix as I have no idea how to solve the questions like. It takes 54 mins for 4 people to paint 5 walls how long would it take 6 people to paint a billion walls... And so on.. may as well be a billion, if I can't see the videos I can't answer it anyways!
Please and thanks
Also this is the video under the "stuck/hint" section
