If your cafeteria is open from 11 am to 1 pm and serves 150 customers with 100 seats, how many times do the seats turn over during this period?

To determine how many times the seats turn over during the cafeteria's open hours, we need to understand the concept of seat turnover, which refers to how many times a seat is filled by different customers during a specific period.

In this case, the cafeteria operates for 2 hours (from 11 am to 1 pm) and serves a total of 150 customers. With 100 seats available, we can calculate the turnover rate using the formula:

Turnover = Total Customers Served / Number of Seats

Substituting in the values:

Turnover = 150 customers / 100 seats = 1.5

This indicates that each seat, on average, is occupied 1.5 times during the 2-hour period. Therefore, the correct answer reflects the calculated seat turnover, showing that each seat served not only one but also some additional customers within that time frame, leading to increased efficiency in seating and serving within limited operating hours.
