A bug is crawling on the coordinate plane from )7,11) to (-17,3). The bug travels at a constant speed of one unit per second everywhere but in quadrant II (with negative x coordinates and positive y coordinates), where it travels at 1/2 units per second. What path should the bug take to complete its journey in minimal time.
