Your cafeteria line requires 8 minutes on the average for each customer to proceed through the line and pay the cashier. The average time space between each customer is 30 seconds. If the line is open for 1 1/2 hours for lunch, how many customers can you serve for lunch?​

Answer:

You can serve 81 customers for lunch during the 11,5 hours opening.

Explanation:

11,5 hours is 690 minutes.
Each customer takes 8,5 minutes (8 + 0,5)

690 / 8,5 = 81,17

As we can't serve "part" of customer:

81,17 ≈ 81 customers
