Answer:
No customer would have to wait
Step-by-step explanation:
The average rate at which customers arrive is 12 customers per hour. This means that in an hour, 12 customers arrive.
The average rate of serving is 15 customers per hour. This means that in an hour, 15 customers are served.
Since the number of customers that are served is greater than the number of customers that arrive within the same time, no customer will have to wait.
Answer:
Step-by-step explanation:
Given:
Rate of arrival of customers = 12 customers/hour
Rate of serving customers = 15 customers/hour
Using the conservation formula,
Rate in = Rate out + accumulation
Accumulation (customers waiting) = rate in - rate out
= 12 - 15
= - 3 customers/hour
Therefore, no customers have to wait.
