How many centuries would it take for humans originating in africa to travel to china some 1 km away?

This is an awkward funny question but nonetheless answerable. 10 thousand kilometers away at a rate of 1 km a year. thats 10 thousand years. and 10 thousand years is 100 centuries. 100 centuries is the answer.

At an average rate of 1 km per year, it would take
10,000 years to migrate 10,000 km.

10,000 years = 100 Centuries

(Also, between 400 and 500 generations ?)

(10,000 km)/(1 km/yr) * (1 century)/(100 yr) = (10,000/100) centuries
= 100 centuries

1 × 10² centuries

Step-by-step explanation:

Given data

The rate of travel is equal to the distance traveled divided by the time elapsed (t).

r = d/t

t = d/r = 10,000 km / (1 km/y) = 10,000 y

1 century is equal to 100 years. 10,000 years are:

10,000 y × (1 c/ 100 y) = 100 c = 1 × 10² c

100 years

Explanation:

10,000 divided by 100 equals 100
