20. A family from Indianapolis, Indiana, is planning a vacation to see relatives in Springfield, Missouri. They check a road atlas and find that the distance between these two cities is 428 miles, which they decide is too long for a one-day drive. St. Louis, Missouri is "between" these two cities, so the family decides to drive to St. Louis on the first day of their vacation. The family checks a road map and finds that their first day's drive will be a distance of 242 miles, and the drive from St. Louis to Springfield on the second day will be 217 miles. Explain the apparent discrepancy in their findings. MISSOURI Springfie
