	The Beach Race

Activity Overview

This beach race begins from a point 4 kilometers out to sea from one end of a 6-kilometer beach and finishes at the opposite end of the beach. Contestants must swim to a point along the beach and then run to reach the finish line. I can swim at 4 km/h and run at 10 km/h. Where should I aim to land on the beach so as to minimize my total time for the race?
