Answer:

The continents moved by 1.905 centimeters each year.

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

In the past 100 years, scientists measured the movement of the continents to be 190.5 centimeters. How much it moved in a year?

100 years - 190.5 centimeters.

1 year - x centimeters

[tex]100x = 190.5[/tex]

[tex]x = \frac{190.5}{100}[/tex]

[tex]x = 1.905[/tex]

The continents moved by 1.905 centimeters each year.
