Question $1(1$ point$)$

"Little's Law is a theorem that determines the average number of items in a stationary queuing system, based on the average waiting time of an item within a system and the average number of items arriving at the system per unit of time." Little's Law can be represented as:

Inventory $=$ Flow Rate $$ Flow Time

Inventory $=$ Flow Rate $+$ Flow Time

Inventory $=$ Flow Rate $x$ Interarrival Time

Inventory $=$ Interarrival Rate $+$ Interarrival Time
