Customers arrive at a fast-food restaurant with one server according to a Poisson process at a mean rate 30 per hour. The server has just resigned, and the two candidates for the replacement are X (fast but expensive) and Y (slow but inexpensive). Both candidates would have an exponential distribution for service times, with X having a mean of 1.2 minutes and Y having a mean of 1.5 minutes. Restaurant revenue per month is given by $6000/W, where W is the expected waiting time (in minutes) of a customer in the system.

Determine the expected waiting time of a customer in the system by hiring either x and y.
