5. A tectonic plate in Earth's crust moves at a
constant rate of 4 centimeters per year. In a
different part of the world, another tectonic
plate moves at a constant rate of 30
centimeters in ten years.

Is this a proportional relationship? please give explanation

Respuesta :

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!
