where the hell did you get 500 from?

@vikastone: If you are referring to 2 minutes or so into the video, I am doing rate times time for the return trip, which is 5(100 - x). 5 times 100 is 500. You didn't specify where exactly you are confused. If it's somewhere else in the video, let me know where.

hi can you help me with this problem please, thank you.----------------- If the speed of an experimental car is decreased by 8km/h it completes a 140 km trip in 2 hours more than had it been traveling at its usual speed. Determine its usual speed.

Thank you very much for posting these helping videos... They have really helped my child understand how to solve rate, time and distance problems with much more ease... Again, thank you :)))))
