Hint: Columbus discovered America in 1492.

This solution refers to the year 2022 and may need to be adjusted, if you are reading it later. First, we calculate the time that has passed since the discovery of America in 1492:

$2022-1492=5302022-1492=530$

Computethe distance in centimeters

$2\text{cm}\cdot 530=1060\text{cm}2\backslash ,\backslash text\{cm\}\backslash cdot530=1060\backslash ,\backslash text\{cm\}$

Convert cm into m.

$1060\text{cm}\cdot {10}^{-2}=10.6\text{m}1060\backslash ,\backslash text\{cm\}\backslash cdot10^\{-2\}=10.6\backslash ,\backslash text\{m\}$

The distance has already increased by 10.6 m since America was discovered.

Convert m in cm.

$5.00\text{m}\cdot {10}^2=500\text{cm}5.00\backslash ,\backslash text\{m\}\backslash cdot10^2=500\backslash ,\backslash text\{cm\}$

Determine the number of years.

$500\text{cm}\mathrm{/}2\text{cm}=250500\backslash ,\backslash text\{cm\}/2\backslash ,\backslash text\{cm\}=250$

It will take 250 years to add another 5.0 m of distance between the continental plates.
