Voting $($i$)-$ one server

In past presidential elections in the United States, very long wait times have been witnessed at precincts $($voting stations$)$ in states that ultimately decided the election $($Florida in $2000$ and Ohio in $2004).$ In NYC as well, some voters complained about the long lines in some precincts, with most complaints coming from precinct A$.$

$$

In $2016,$ the average number of voters arriving at Precinct A was $27$ per hour and the arrival of voters was random. NYC had deployed $1$ voting machine in Precinct A$.$ Suppose service times were also random and that each voter spent on average $2\mathrm{.}0$ minutes in the voting booth $($this is the time needed to cast her$/$his vote using a voting machine$).$ What is the average time a voter waits before he$/$she can go in the voting booth?
