A) 3:00 B) 4:00 C) 5:00 D) 6:00 E) 7:00 6:00 in evening in Chicago = 7:00 in evening in New York. So, the train was in Chicago 7:00 in the evening, New York time. The trip took T=D/R=840/60=14 hours. Therefore, the train depart from New York at 7:00  14 hours = 5:00 in the morning, New York time. Answer: C.

A. 3:00 B. 4:00 C. 5:00 D. 6:00 E. 7:00 It's a bit ambiguous as to what exactly "Chicago time is one hour earlier" actually means. Does it mean that it's "earlier" there, by one hour  in which case the time in NY is 7 PM  or does it mean that chicago time is "earlier"/faster than NY time by one hour (in which case the clock is 5PM in NY). In fact, the info specifically refers to Chicago time being one hour earlier (what does that even mean? For time to be earlier? Extremely poor choice of words), this creates ambiguity. Of course, common sense tells us that geographically, Chicago is to the west of NY so the second scenario doesn't make sense, but if we don't use "common" wordly sense, we could eroneously conclude that A  3:00 is the correct answer. Which, of course, it's not. And since the GMAT doesn't test skills in geography, being punished for not knowing where different cities in the US are located is pretty much laughable. For instance: "Sprinter X finished earlier than sprinter Y" means that sprinter X is faster than Y, which means that it takes sprinter Y longer to arrive at the finish line than it takes sprinter X. Apply this logic to time zones for NY and Chicago: "Chicago time is earlier than NY time", this means that it takes NY time longer to arrive at the same time than it takes Chicago. So if it's 6PM in Chicago, NY will be at 6PM in one hour, which means it's 5PM in NY right now. But this is not the first time that I feel like GMAT uses vague wording, it's very annoying.

For whomever reads this next, comparing finishers of race to time zones is a fallacy of equivocation. "Earlier" in context of a race is not the same as "earlier" in time zones. Earlier always signifies East, and West always means behind. Even if you didn't know where the other city is located, you can deduce that since New York is on one coast, there must be one other direction to go, West.

Even if you didn't know where the other city is located, you can deduce that since New York is on one coast, there must be one other direction to go, West. Actually, I do agree with aeglorre. In case of time zones, we use ahead (not earlier) and behind. Ahead implies east and behind implies west. "Chicago time is earlier than NY time" is ambiguous. Nonambiguous representation would be "New York time is an hour ahead of Chicago time". This implies that 7:00 am in New York is 6:00 am in Chicago. And yes, considering the international nature of GMAT (the applicants and the schools that accept GMAT score), the applicants cannot be expected to know that New York is on the east coast of US. It has to be clearly mentioned. I think this is an OG question and hence, must be quite old. I don't think you will find such ambiguity in GMAT now.

840m / 60mph = 14hrs
6pm = 1800
18001400 = 0400 Chicago time
NY time = Chicago time + 1hr (or 0100 to keep the formatting the same)
0500 = 5am
