Question

From 3:00 p.m. to 8:00 p.m., when customers arrive at a rate of 70 per hour at the local K-Star Supermarket, how does this affect the checkout process, and what factors should be considered in managing customer flow during these hours?

Answer 1

Customers arriving at a rate of 70 per hour at the K-Star Supermarket between 3:00 p.m. and 8:00 p.m. will have an average time between two successive arrivals of approximately 51.4 seconds. On average, it will take around 2 minutes and 34 seconds for three customers to arrive when the store first opens.

Step-by-step explanation:

In this scenario, customers are arriving at a rate of 70 per hour at the K-Star Supermarket between 3:00 p.m. and 8:00 p.m. To determine the average time between two successive arrivals, we divide 60 minutes by the arrival rate of 70 per hour. This gives us approximately 0.857 minutes or 51.4 seconds.

When the store first opens, we can calculate the time it takes for three customers to arrive by multiplying the average time between arrivals by three. So, 0.857 minutes x 3 = 2.571 minutes or 2 minutes and 34 seconds on average for three customers to arrive.
