Answer :
On average, 30 people enter Starbucks every hour, given that one customer arrives every two minutes.
To determine how many people enter Starbucks every hour, we can use the information provided to calculate the rate at which customers arrive at the store. If a person spends 6 minutes at Starbucks on average and there are 16 people in Starbucks on average, we can deduce that these 16 people are spread over a 6-minute interval. This is because if one person leaves after 6 minutes, a new person arrives to maintain the average number present.
According to Solution 5.11 part (a), we expect on average one customer to arrive every two minutes. Therefore, in an hour, we can calculate the total number of customers by dividing 60 minutes by the 2-minute arrival rate.
Total number of customers per hour = 60 minutes / 2 minutes/customer
= 30 customers per hour.
So, on average, 30 people enter Starbucks every hour. This aligns with the given information that one customer arrives every two minutes on average, and it would take six minutes for three customers to arrive, indicating a consistent inflow of customers.
