What is the minimum age of Earth. We are given a hint of: If the age of Earth were equal to one calendar year, the 1492 arrival of Christopher Columbus in America would have occurred at five seconds to midnight Dec. 31.
That confuses me even more.
According to Wikipedia, the age of the earth is 4.54 billion years (within 1%).
According to the analogy, the age of the Earth in years is:
= 3.3 billion years
A pretty close analogy.posted by MathMate
