Answer 1

Answer:

Field

Field is eroding 4 times faster than the mountain.

Step-by-step explanation:

$y$ = The amount of erosion in millimeters

$x$ = Number of years passed

$y=0.5x\\\Rightarrow \dfrac{y}{x}=0.5$

The rate at which soil is eroding in the mountain is 0.5 millimeters per year.

The rate at which the field is eroding is 2 millimeters per year.

The field is eroding faster than the mountain.

$\dfrac{m_f}{m_m}=\dfrac{2}{0.5}\\\Rightarrow m_f=4m_m$

So the field is eroding 4 times faster than the mountain.
