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.

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
