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

`-46` meters per year.

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}=(y_2-y_1)/(x_2-x_1)`

`\text{Rate of change}=(1780-2010)/(5-0)`

`\text{Rate of change}=(-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.
