For exercise, Ruth likes to walk. She lives in Chicago where many streets run directly north and south or east and west. Ruth walks with a pedometer, a device that calculates the distance she has walked. One day she decided to walk the perimeter of a large square. She walked 3 miles east. Then she turned and walked 3 miles south. A sudden rainstorm prevented her from completing the square. She had walked 6 miles when she called her husband to ask him to pick her up. To the nearest tenth of a mile, what was the straight-line distance from Ruth’s starting point when she stopped?
