Problema Solution
A certain mountain has an elevation of 19,854 feet. In 1913, the glacier on this peak covered 6 acres. By 2000 this glacier had melted to only 1 acre. Assume that this glacier melted at a constant rate each year. Find this yearly rate.
Answer provided by our tutors
in 2000 - 1913 = 81 years the glacier has melted 6 - 1 = 5 acres.
So the right would be 5 acres per 81 years which is proportional to x acres per 1 year thus we find
5/81 = x/1
x = 0.062 acres per year.
