I'm looking forward to the launch, from both a student's and a teacher's perspective. Sam, if Kaplan has any more million dollar slots left, perhaps you can refer me to the hiring manager? :)

Oh well. You are of course right about the miles being minutes in the train problem. I'll be sure to double check my math if I put any more problems on the blog.

Perhaps I'm missing something. My equation works out as follows: 10t+10=15t Thus 5t = 10 so t=2 hours. Am I missing something or are you? Hi

But I am a pretty good proofreader! Great article - right on track. Hey Sam - I must admit I’ve missed more than one train, and I rely heavily on calculators and spreadsheets when it comes to math.

Your math skills are much appreciated. Apparently the slowest train in TeachStreet City this morning was train C: me. Bruce, thanks for pointing that out. Your math skills are much appreciated.

But the answer to this one is not 20 minutes. Q: "how long will it take Train B to catch up with train B?" A: no time at all. I’m one for whom the test would probably get easier and easier.
