What is the required number of seats if your cafeteria is open from 10:30 am to 1:30 pm and you serve 200 customers with a turnover rate of 1.5 times per hour?

To determine the required number of seats in the cafeteria, it is essential to calculate the total customer flow during the operating hours and the turnover rate. The cafeteria is open for three hours, from 10:30 am to 1:30 pm. During this time, 200 customers need to be served, and the turnover rate is 1.5 times per hour.

First, we can calculate the total number of seat turnover in the three-hour period:

• Since the turnover rate is 1.5 times per hour, this means each seat can accommodate 1.5 customers every hour.

• Over three hours, the total turnover would be (1.5 \times 3 = 4.5) customers per seat.

Next, to find out how many seats are needed to serve 200 customers, we can set up the equation based on the total number of customers and turnover per seat:

[

\text{Number of seats} = \frac{\text{Total customers}}{\text{Total turnover per seat}} = \frac{200}{4.5}

]

Calculating this gives:

[

\frac{200}{4.5} \approx 44.44
