Answer:
a. [tex]3.04\times 10^{-8}m[/tex]
b. = 40 km/ million years
Explanation:
The computation is shown below;
According to the question, Data provided in the question
Average speed = 4.0 cm / per year
Distance move in 1 second at this speed
Based on the above information
a. For distance move in 1 second is
As we know that
[tex]d_1 = v_g \times t\\\\ = 4\ cm \times \frac{1}{100\times 365.25\times 3,600} \times 1\s\\\\= 3.04\times 10^{-8}m[/tex]
b. For speed per kilometer per million years is
[tex]v_1 = 4\times \frac{10^6}{10^5} \\\\[/tex]
= 40 km/ million years
