There are two services between Sandpoint and Genville: a fast hovercraft service which takes 50 minutes and a slow ferry which takes 1 hour 40 minutes. They both stop in port for 20 minutes at each end before starting the return journey. They start out from Sandpoint together at the same time each morning.
For how long has the slow ferry been sailing before it meets the hovercraft coming back? (Answer to the nearest minute if necessary).
