14. [10 marks] A windsurfer has broken down at sea (again). They wish to get back to their car as quickly as possible. They are 400 m offshore and have drifted 300 m downwind from their car. They can walk about 4 times faster than they can swim. Assuming they swim in a straight line and then walk along the shore, what route should they take to get back to their car as soon as possible? Include a sketch to define your variables
