[Question]At a station, a train comes every 5 minutes leaving 200 passengers and taking 320 others. How many different passengers step on and off a train at the station within an hour?
[Answer]At every passenger exchange there are 200 + 320 = 520 different people. One hour is 60 minutes, so during one hour, a train comes 60 minutes / hour / 5 minutes / train = 12 times. So during one hour, 12 trains * 520 passengers / train = 6240 different passengers step on and off the train. The answer is 6240.
