Question

hi, plz answer this....
If shoppers enter a store at an average rate of r shoppers per minute and each stays in the store for average time of T minutes, the average number of shoppers in the store, N, at any one time is given by the formula N=rT. This relationship is known as Little's law.

The owner of the Good Deals Store estimates that during business hours, an average of 3 shoppers per minute enter the store and that each of them stays an average of 15 minutes. The store owner uses Little's law to estimate that there are 45 shoppers in the store at any time.

Answer 1

Answer:

Formula = $N=rT$

r = rate of shoppers

T = Average time

N = Average number of shoppers

We are given that an average of 3 shoppers per minute enter the store and that each of them stays an average of 15 minutes. The store owner uses Little's law to estimate that there are 45 shoppers in the store at any time.

So, r = 3

T = 15

$N=rT$

$N=3 \times 15$

$N=45$

Hence shown
