Answer:
The solution of the given problem is provided in the following subsection.
Explanation:
According to the question,
The change in the height of the glacier will be:
= [tex]1780-2010[/tex]
= [tex]-230[/tex]
Change in time,
= 5 years
Now,
The rate of change will be:
= [tex]\frac{m}{years}[/tex]      ∵ (1 year = 12 months)
= [tex]\frac{230}{5}[/tex]
= [tex]-46 \ m/years[/tex]
or,
The rate of change will be:
= [tex]\frac{m}{months}[/tex]     ∵ (5 years in months = 5×12 months)
= [tex]\frac{-230}{5\times 12}[/tex]
= [tex]\frac{-230}{60}[/tex]
= [tex]=3.83 \ m/months[/tex]
