Question

A bank finds that the average number of people waiting in line during lunch hour is 10. On average, during this period, 2 people per minute leave the bank after receiving service.
On average, how long do bank customers wait in line?

Answer 1

Answer:

5 minutes.

Step-by-step explanation:

We have been given that a bank finds that the average number of people waiting in line during lunch hour is 10. On average, during this period, 2 people per minute leave the bank after receiving service.

We will use flow time formula to solve our given problem.

$\text{Flow time}=\frac{\text{Number of units produced}}{\text{Duration of time period}}$

$\text{Flow time}=\frac{10}{2}$

$\text{Flow time}=5$

Therefore, on average bank customers wait in line for 5 minutes.
