Answer:
No
Step-by-step explanation:
This is not a proportional relationship because 30 centimeters/10 years=3 so the other tectonic plate in the different part of the world moves 3 centimeters per year, while the other moves 4.
In other words, 4 is not equal to 3, so it is not a proportional relationship. The first tectonic plate mentioned would move 40 centimeters in 10 years while the other would only move 30 centimeters, so they are not equal.
Hope this helped!
