can you be a lil more specific with what you're having issues with? which part of the logic still eludes you?

having a strong basic physics background (especially classical mechanics) really helped me in these types of problems.
I beat the GMAT! 760 (Q49/V44)

Raunek,

The solution over here is that you understand the basics. You are talking about "relative speed" questions, these are not at all difficult. Post a typical problem you are having trouble with and why you are having trouble with it and I am sure one of the BTG members can give you an answer that clears your doubt.

i have the same problems too ... i found a pretty good solution to different rates problems

separation/ meeting situation
D1 + D2 = D apart

overtake situation
D1=D2

roundtrip situation
Dout + D back

Raunek,

You should go to a library and get a basic algebra book. They have some really great explanations as to how and why things are to be arranged.

Check out algebra by Robert Blitzer.
