Question

during the two hours of the morning rush, 100 customers per hour arrive at the coffee shop. the coffee shop has a capacity of 80 customers per hour. at what rate does the queue of customers at the coffee shop grow during this time?

Answer 1

Answer: The average growth rate of customers in the queue is 30 per hour

Explanation:

Given that:

Step1:

number of customers arrived per hour = 100

The capacity of the coffee shop = 80

Step2:

let us assume at the beginning, the coffee shop is empty. Only 80 of the 100 customers that arrive in the first hour may be attended to. There are 20 consumers in line, so they must wait for the next hour.

Another 100 clients show up during the second hour, but there are already 20 people in line from the first hour. As a result, although the coffee shop needs to serve 120 customers, it can only do so at a rate of 80 each hour. Forty (40) consumers must wait in line for the next hour.

Therefore for two hours, The coffee shop's customer line is extending with an average growth rate of:

(20 customers per hour + 40 customers per hour) / 2 hours = 30 customers per hour

Therefore, the queue of customers grows at a rate of 30 customers per hour during the morning rush.
