On a typical day flight at a local airport arrive at a rate of 10 every 15 minutes at this rate how many flights would you expect to arrive in one hour
There are 60 minutes every hour. That means there are 4 intervals of 15 minutes in one hour (60/15 equals 4). Each interval brings in 10 flight, so if we multiply the 10 flights by the 4 intervals, we end up with 40, which is our answer
