Challenge Problem A bike path starts on one side of the parking lot, goes
around a small pond, and comes out on the other end
of the parking lot. Following the path, a biker rides
100.0 meters directly east, then turns south and rides
200.0 meters. From there, she turns and rides 150.0
meters at an angle of 30.0° south of west. Turning one
last time, she rides 250.0 meters at an angle of 60.0°
north of west. What is her final displacement (distance
and direction) from her starting point?
