bagaimana kah rumus dan jawabannya ​

There is 1000m to represent 4.5billion years.This means 1m represents (4500,000,000/1000) 4,500,000 years. For 2 billion years: 2,000,000,000/4,500,000=444.44m Written history: 10,000/4,500,000=0.0022m from the end.

The distance of 444.4 meters represents 2 billion years on timeline and from the end , the written history began almost 2 x 10⁻³ meters = **0.002 meters **before the present time.
What is unitary method?
The unitary method is a process of finding the value of a single unit and based on this value, we can find the value of the required number of units .
Given is a theory based on modern science which says earth is 4.5 billion yrs old and written human history extends about 10,000 yrs back of the present.
In 1000 meters there are 4.5 billion years.
Then, in one meter there will be → 4.5/1000 → 0.0045 billion years.
This means that in 1000 meter long timeline scale, 1 meter of distance will represent 0.0045 billion years.
Now -
**0.0045 billion **years = **1 meter **distance in timeline scale.
1 billion years = (1/0.0045) meter distance in timeline scale.
2 billion years = (1/0.0045) x 2 = 444.4 meters of distance in timeline scale.
And -
0.0045 billion years = 0.0045 x 10⁹ years = 1 meter distance in timeline scale.
1 year = (1/0.0045 x 10⁹)
In **10000 yrs **= (1/0.0045 x 10⁹) x 10000 = (2 x 10⁶)/10⁹ = 2 x 10⁻³ meters.
From the end, the written history began almost 2 x 10⁻³ meters = 0.002 meters before the present time.
Therefore, the distance of 444.4 meters represents 2 billion years on timeline and from the end , the written history began almost 2 x 10⁻³ meters = **0.002 meters **before the present time.
