Diane has been asked to consider plans to add the retrieval of larger tooling fixtures to her duties.She anticipates that there would be an average of 12 tooling fixtures per day requested.Each tooling fixture would take Diane 4 minutes to retrieve. What is the average waiting time,in minutes,if Diane continues to be the only worker that would retrieve the small tools as well as the larger tooling fixtures?
A) 3.50 minutes
B) 7.00 minutes
C) 9.25 minutes
D) 64.00 minutes

To calculate the average waiting time, we need to consider both the time it takes for Diane to retrieve the tooling fixtures and how many tooling fixtures are in line ahead of the current request. Since we know that there will be an average of 12 tooling fixtures per day requested, and each fixture takes 4 minutes to retrieve, we can calculate the total time per day spent on retrieving tooling fixtures as follows:

12 tooling fixtures/day * 4 minutes/tooling fixture = 48 minutes/day

Assuming that Diane works 8 hours per day (480 minutes), the average waiting time for a tooling fixture request would be:

48 minutes/day / 12 tooling fixtures = 4 minutes/tooling fixture

Therefore, the average waiting time for a larger tooling fixture request would be 4 minutes (the same as the time it takes Diane to retrieve each fixture). However, if there are other small tooling requests in line ahead of the fixture request, the waiting time would be longer. Taking into account the time it takes to retrieve small tools, it is plausible that the average waiting time for a tooling fixture request would be closer to 9.25 minutes, as stated in option C.
