Answer:

\frac{4}{9}

Step-by-step explanation:

First, we gather the data:

The model is a single M/M/1 landing strip with \mu = \frac{2}{3}

This based on the assumption that service times are exponential.

Then, we must find the maximum rate such that w_{q} \leq 3

Using the M/M/1 table, we find that:

w_{p}  = \frac{\rho }{(\mu (1 -\rho)  } \\ \frac{\lambda }{\mu (1 - \lambda  } \leq 3

if and only if

\lambda\leq \frac{3\mu ^{2} }{(1 + 3\mu) }

=\frac{4}{9}
