Bob, Fred, and Jim are driving three identical cars in a demolition derby. Bob is driving due south at 22 mph, Fred is driving northwest at an angle 107 degrees clockwise from north at 19 mph, and Jim is driving north east at an angle 192 degrees clockwise from north at 24 mph. They all smash into each other at the same time. At what exact speed and direction does the resultant crash move?
