When flying to Savannah this week on a small plane, I looked out the window and noticed that a typical automobile almost directly below appeared to be about the size of a dime held at arm's length. Estimate how high the plane was above the ground. Be sure to clearly state your assumptions and how you came to the numbers you estimated, since grading on this problem will be mostly based on your reasoning, not on your answer.
