Bees and Trains: A distance problem

I'd suggest the problem be done both as an infinite (geometric) series as well a simple distance-speed-time problem. To the OP, for what...

Ok to our problem. If triangle NPR is flipped (or rotated) about the vertical line AB, N will move to the right of B as far as it is to...

Ok so I rotated about an axis going in through the page, perpendicular to it. You're asking me to rotate about the dashed line, which is...

Why do you say so? I can't understand. Of course RN = KQ. (do you mean flip about the thin black line marked with distances ##x_1,x_2##?)
