You can put this solution on YOUR website! This lesson deals with the very same general problem:
http://www.algebra.com/my/Uniform-Rates-Travel%3A-Two-Speeds-Differ-by-Constant-Same-Distance.lesson?content_action=show_dev
The data table would be like:
_________________speed___________time___________distance
Fast Plane_______r+10____________t-2____________(r+10)(t-2)
Slow Plane_______r_______________t______________rt
Understand that lesson, and you can solve any problem of this type.
