Question

A glacier advanced down a mountain from an elevation of 2010 m to 1780 m in 5 years. what was the glaciers rate of change

Answer 1

The rate of change is : 

(2010 - 1780)/5 = 230 / 5 = 46

46m per year

Answer 2

Answer:

$-46$ meters per year.

Step-by-step explanation:

We have been given that a glacier advanced down a mountain from an elevation of 2010 m to 1780 m in 5 years.

$\text{Rate of change}=\frac{y_2-y_1}{x_2-x_1}$

$\text{Rate of change}=\frac{1780-2010}{5-0}$

$\text{Rate of change}=\frac{-230}{5}$

$\text{Rate of change}=-46$

Since the glacier is melting down, therefore, the glacier's rate of change would be $-46$ meters per year.
