Its a simple reflection problem.... since the shortest distance between two points is a line, just reflect one of the cities through the railroad line and connect the two cities by a line. The point where the line intersects the railroad line is where you put it...
By the way, I wasn't suggesting solarflare's answer was incorrect. I was just showing how you solve it, since the brute force method would be a differentiation problem and there is a nice, elegant solution to problems like these using simple ratios.
(I never get here in time to actually answer a problem -- except for that one -- so I wanted to contribute, however minor :) )
When I look at a problem like that, the first thing I do is figure out what methods I could use to solve it completely. Of course when I saw minimize I thought differentiation, but it turned out that it would have been horrifically ugly as galathaea pointed out. So I stuck with x/? = y/n-?, and solved for ?.Quote:

I am trying to think about the funiest question for You Ms/Mr Solarflare:D. And remember to try your best to give out the correct answer to be in the first rank Okay ?
Yes.Quote:

I will post a question later. :) :D
You seem to not have paid attention to the fact that I didn't trust you in the first place and therefore did not write anything in that PM you forwarded that wasn't already known by the person in question or that would go over the line, not that I ever done that in a PM. However, I don't like you much...really. :mad:Quote:

I'm not even going to pretend I understand what's going on in this thread right now.
Fight, fight, come on, we want to see a good fight! :D:p;)Quote:

:rolleyes:
But I don't know either what this is about. :confused: :(
Let's just say that WFranc forwarded a PM about the previous issues I had with Gabriel, I didn't know for sure with what intentions but based upon "Oh Gosh, you have forgoten what happened, Simon", it were apparently no good intentions.
WFranc : Most of us who post in CodeGuru, are working adults and you should realise by now, most of them have a degree. However, when we are posting in the General Discussion forum(Chit-chat), we automatically 'shift' into our pseudo-self which seem to be very funny characters, actually most of us here are very serious people when it comes to work.
I hope you do not pm people unless it is necessary. In the very start when you pm'ed me, it is not that I'm unfriendly so I'm not replying to your PMs, it is because I'm afraid you would keep pm me more of such stuff.
