According to modern science, Earth is about 4.5 billion years old and written human history extends back about 10,000 years. Suppose the entire history of Earth is represented with a 100-meter-long timeline, with the birth of Earth on one end and today at the other end. a. What distance represents 11 billion years? b. How far from the end of the timeline does written human history begin?

Question

Answer:

I believe the answer to A. is 244.44 meters long. 100 meters equals earth's timeline of 4.5 billion. 11 divided by 4.5 billion equals 2.4444. Multiply by 100 for the meters and you get 244.44 meters.
