At the beginning of a race, a yacht crosses the start line and sails in
westerly direction at a speed of 4 m s1. The current of the sea is flowing at
2 m s1 towards the northeast. Calculate how far [8 marks] and in what
direction (relative to west) [8 marks] the yacht has travelled after 10
minutes from its crossing the start line.

Steve,
(4,0) + (1.4,1.4) = (2.6,1.4)
= 2.96 m/s at W28.3°N
After 10 minutes (600 seconds) the distance traveled is 1772m
