As Sam drove home from baseball practice, he began to wonder just how far he lived from the field. It typically took him 45 minutes to make it home. His mind began to tick, and Sam determined that the distance he drove along roads from the baseball field to his driveway was not representative of the actual distance between the two locations. What did his grandfather used to say? It was something about “as the crow flies” and displacement. He would have to look it up, or maybe even call his grandfather. How could Sam determine the distance he drove and the true displacement between the two locations? Be sure to explain fully, as well as solve mathematically.
