A) The Burger King employee is busy  75% of the time.

B) The average number of customers waiting to be helped is 2.25.

C) The customers have an average time of 11.25 minutes waiting on the line.

Explanation:

let x be the mean arrival rate = 12 customers per hour

let y be the mean service rate = 16 customers per hour

A) the  percentage of the time is the Burger King employee busy is given by:

(12/16)*100

= 75%

Therefore, the Burger King employee is busy  75% of the time.

B) the average number of customers WAITING to be helped is given by:

x^2/y(y-x)

= (12^2)/[16(16-12)]

= 2.25 customers

Therefore, the average number of customers waiting to be helped is 2.25.

C) the average waiting time for customers in line is given by:

x/y(y-x)

= 12/[16(16-12)]

= 0.1875 hours

= 11.25 minutes.

Therefore, the customers have an average time of 11.25 minutes waiting on the line.
