According to science, earth is about 4.5 billion years old and written human history extends back about 10,000 years. suppose you represent the entire history of earth with a 100-meter-long timeline, with the birth of earth on one end and today at the other end. what distance represents 4 billion years? how far from the end of the timeline does written human history begin?

4 billion years- 88,88 meters

10,000 years- 2,22*10^-7 meters

Step-by-step explanation:

In order to calculate this you just have to do a rule of three, when 4.5 billlion is 100 meters, and we just have to calculate how many meters are 4 billion and 10,000 meters:

Now, 4.5 billions are in stadar form: 45,000,000,000 so we will use this to calculate with the rule of three of 10,000 years:

So those two would be the answers.

do you mean add both of the equations together

because if you do the answer is 10x-5
