A geologist doing field mapping is returning to her base camp through the woods. She was supposed to walk at an azimuth of 40 degrees for 20 min. She accidentally walked at an azimuth of 55 degrees for 15 min, then realized she needed to correct her direction. If she walked at a speed of 4.0 km/h, at what bearing should she travel to get back to the base camp? How much farther did she have to travel following this route compared to the original direct path?
