Question

Students are going through a three-step process to obtain their ID cards.

Answer 1

Answer:

The correct answer is both A and C

Explanation:

Solution

Given that:

The Process 1 Registration, Capacity = 0.5 registration per minute (1/2)

The Process 2 Cashier, Capacity = 1*3 / 10 = 3/10 = 0.3 payments per minute

The Process 3 , Photo ID, Capacity = 1*4 / 20 = 0.2 ID per minute

Now

The Time taken for process a unit is minimum of Demand rate / Lowest process capacity

so, the flow rate = 0.2 student per minute or 5 minute per student

Thus,

The total time = 20 * 5 = 100 minutes.
