T. {11 points) Copper is standing at the westernmost point of the lake with radius 120 meters when he spots a duck across. To get to the duck, he can swim or run around the lake. He swims at a speed of 6 meters per second and runs at a rate of 12 meters per second. If he swims to point B in a straight line and runs around the lake from B to C. nd the angle 6' shown which will minimize his time to reach the duck. Make sure you justifyr using calculus why the answer you found gives the minimum time. Note: The picture is not to scale
