I fully read it, and i understand it all the way to the last step, and then i can't follow.

R2-M is the relative speed on the second set of observations (28.4kts). Z-Y is 2 hours total.. so the distance of Z-Y is 56.8 miles.

So.. uhh.. what determines how far along Z-Y that A is being placed to find B?
