An airport has a plane landing every 55 seconds. If an average flight holds 245 passengers How many passengers arrive at this airport in a day. Show your work
There are 60 seconds in a minute and 60 minutes in an hour, so there are 60 * 60 = 3600 seconds in an hour.
Therefore, there are 3600 / 55 = <<3600/55=65.4545>>65.4545 planes landing in an hour.
Since there are 24 hours in a day, there are 65.4545 * 24 = <<65.4545*24=1570.9091>>1570.9091 planes landing in a day.
So, a total of 1570.9091 * 245 = <<1570.9091*245=384659.0728>>384659.0728 passengers arrive at this airport in a day. Answer: \boxed{384659}.
