Question

A hiker on a trek needs to cross some rough terrain. In order to do so, she has to walk east for half a mile, then head 30o north of east for a quarter mile, then finally she can reach her destination by heading due west for a mile. Because of the indirect path she had to take to reach her final destination, she traveled a pretty far distance. But how far did she actually get from her starting point, as the crow flies?
