Main Question or Discussion Point
A sailor in a boat 10 km off a straight coastline wants to reach a point 20km along the coast in the shortest possible time. Toward what point on the shore should he head if he can row at 4 km/h and run at 12 km/h?
i believe this involves optomizeation as well ralated rates but i am unsure as to how to get the equasion to maximize.
x=10km
sailor   (straight coast)
dx/dt=4 km/h 
 y= 20 km dy/dt= 12 km/h
