The time it takes for a ferry to reach a summer resort from the mainland is Normally distributed with mean 2 hours and standard deviation 12 minutes.

What should be the advertised duration of the trip (in minutes) if the ferry management does not want to be late on more than 5% of the trips but would like to minimize the advertised duration?
