A man in a canoe need to travel 600 m on the Bay of Fundy from his favourite fishing spot to his cabin. This trip takes 4 minutes when the tidal motion is negligible. However on this day the man is facing a strong tidal current that runs toward him at a 30 degree angle to the left of the line between his fishing spot and the cabin. The tidal current flows at 1.5 m/s. 

a. If the man wishes to travel directly across the lake to the cabin in what direction does he need to canoe?

b. How long does the trip take?
