Answer: 3.6 seconds
Explanation: Geologic time is a way of measuring time based on events in the history of the Earth. If we compress this into one year, a single geologic year equals 4.6 billion years because the planet was formed 4.6 billion years ago.
Columbus arrived in the New World in August 1492, 528 years ago.
If 4.6 billion years = 1 year in geologic time,
528 years = 528 X 
=3.6 seconds
<em>(I broke the year down into seconds by breaking it down into days, then hours, minutes and seconds because the value is very small)</em>

<em>So, if we compress geologic time into a single year, only 3.6 seconds have elapsed since Columbus arrived in the New World</em>

Most historians agree that the space race ended on 20 July 1969 when Neil Armstrong stepped onto the Moon for the first time. As the climax of space history and exploration, the lunar landing led to a triumph for the US.
Wouldn't this be a math question? But anyway, the answer is 3(x-2)(x+1).
To add fractions with different denominators you must convert the denominators into the lowest common factor. Aka the multiple they all go into. You then times the numerator by what you timsed the denominator by to make sure they both have the same denominator.
Example:
2/5+4/10
They both go into 10.
4/10+4/10= 8/10. 2 became 4 because 5x2=10.
I hope this helped!
You could also simplify 8/10 into 4/5z
