Question

2) During a portage, the leader of a scout troop decided to save time by hiking around a

wooded area between the base camp and a lake. The troop reached the lake by walking for
30 minutes on a bearing of N60°E, then for 45 minutes on a bearing of N80°W. The leader
figured that they walked at an average speed of 3km/h. If they could have walked straight
through the forested area at 1km/h, did the troop save any time by going around? If so, how
much?
