- n09n 14y agoNo, he does not say the opposite: >even though the trains arrive with the same frequency, the downtown train departs just a few minutes after the uptown train has departed. Because of this, there is only a narrow time window in which the man is able to get on the uptown train. He should say it like you suggested though.
- brucehart 14y agoYou're right. I was looking at the diagram. Clearly the author accidentally swapped the two names in that sentence.
- alexfoo 14y agoThe description has it the other way. "The solution is that, even though the trains arrive with the same frequency, the downtown train departs just a few minutes after the uptown train has departed. Because of this, there is only a narrow time window in which the man is able to get on the uptown train." s/after/before/ to fix the explanation.
