A) 0.083
B) 0.25
C) 0.167
D) 0.333

Answer 1

The correct service rate per hour when a customer is served in 5 minutes at a fast-food restaurant is 0.083, as there are 12 customers served per hour and the rate is expressed as the reciprocal of the number of customers served.

Step-by-step explanation:

When calculating the service rate for a fast-food restaurant, we convert the service time from minutes to hours. If one customer is served in 5 minutes, we are looking for how many customers can be served in one hour. Given that there are 60 minutes in an hour, we divide 60 by 5 to find the service rate per hour.

The calculation is 60 ÷ 5 = 12 customers per hour. To express this in terms of hours, we take the reciprocal of the number of customers which is 1 ÷ 12. When you perform this division, you get an answer of 0.0833, which when rounded to three decimal places is 0.083.

This is the service rate per hour. Therefore, the correct answer to the question "If it takes 5 minutes to serve a customer at a fast-food restaurant, what is the service rate?" is 0.083.
