Question

Earth consists of a series of relatively thin plates which are in constant motion. These plates move at different velocities. A certain plate moves about 54 mm per year. How many millimeters will the plate move in 65 years?The plate will move ____ mm in 65 year.

Answer 1

In order to determine how much the plate will move in 65 years, we need to multiply the rate at which it moves per year by 65, which is the total time it will spend moving. This is done below:

`\begin{gathered} D=54\cdot65 \\ D=3510 \end{gathered}`

It will move a total of 3510 mm in 65 years.
