1. The problem statement, all variables and given/known data You are standing on an open field 72,0 m away from a straight river. Your tent is 136 m away from you, while being only 8,0m away from the river (on the same side you are on). Before you go back to your tent, you would like to fill your water bottle in the river. What point on the river should you go to in order for the total trip back to your tent to be the shortest 2. The attempt at a solution I would think that I should find some relations between the rates of change of the hypothenuses of the two triangles I made. This should somehow give me the shortest possible lengths of the hypothenuses combined, but I am not sure how to venture into this problem. Would really appreciate it if someone could set me off in the right direction!
