k thx but how did u get (i+j)/ sqrt 2 in the first part n (31,43) in the 4th part??

Velocity vector = Direction vector / Discriminant of the direction vection x Speed. The boat sails north-east, hence 1 i and 1 j.

LOL I actually complicated the whole matter, in the question it was stated that the boat sails with unit vector north and east, unit vector = (1, 0) if it is i. (0, 1) if it is j ... :(
