First figure out how many hours the train traveled. 840 miles at 60 miles an hour is 14 hours. That means the train left New York at 4:00 AM Chicago time, which would be 5:00 AM New York time.

Time taken by the train is 840 / 60 = 14Hrs
Therefore the train must have started at 4:00AM Chicago time, Since Chicago is 1 hr earlier than NY it will be 5:00AM in NY. Hence answer is [spoiler]5:00[/spoiler]

arrival was 6:00 pm, so departure was 4 am Chicago time
NY time = 4+1 = 5 am

We can plug in the answers, which represent the departure time.
Answer choice C: 6am.
6am + 14 hours = 8pm.
Since Chicago is one hour earlier, arrival time is 7pm.
Since the arrival time must be 6pm -- 1 hour earlier -- the departure time must be 6am - 1 = 5am.
The correct answer is B.

7 pm - 14 hours = 7 pm - 7 hours - 7 hours = 12 pm - 7 hours = 5 am
