<human>:  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?
<bot>: How many different people are there at every passenger exchange? ** At every passenger exchange there are 200 + 320 = <<200+320=520>>520 different people.
How many times does a train come in an hour? ** One hour is 60 minutes, so during one hour, a train comes 60 minutes/hour / 5 minutes/train = <<60/5=12>>12 times.
How many different passengers step on and off a train at the station within an hour? ** So during one hour, 12 trains * 520 passengers/train = <<12*520=6240>>6240 different passengers step on and off the train.
