At the beginning of a race, a yacht crosses the start line and sails in

westerly direction at a speed of 4 m s-1. The current of the sea is flowing at

2 m s-1 towards the north-east. 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.

(-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
