Answer :
To maintain an average occupancy of 16 people in Starbucks, with an average stay of 6 minutes per person, 30 new customers would enter each hour.
To calculate the average number of people entering Starbucks every hour based on a given average stay and current occupancy, we use a rate calculation. We were told that on average, one person spends 6 minutes at Starbucks, and there are 16 people on average in Starbucks.
From this, we can infer that the time taken for one person to leave and make room for the next person is the same as the average stay, which is 6 minutes. Therefore, in one hour (60 minutes), we would expect 60 minutes / 6 minutes per person = 10 people to enter to maintain the average occupancy of 16 people.
From the additional reference information provided, each customer arrives every two minutes on average. Thus, in one hour (60 minutes), we would have 60 minutes/2 minutes per arrival = 30 customers arriving.
Comparing both calculations, since the average occupancy must remain at 16 people, but we have 30 customers arriving per hour, we can conclude that 30 is the number of new people entering Starbucks every hour, maintaining the average occupancy.
