Problema Solution
In December 1994, geologists found that the Bering Glacier had come to a stop. Until that time, the glacier had been rushing forward at a rate of up to 300 feet per day. Before the surge began, the glacier was retreating at a rate of about 2 feet per day. If the retreat resumes at the old rate, what integer represents how far the glacier will have moved after 28 days?
Answer provided by our tutors
if the glacier is retreating at a rate of about 2 feet per day then its movement is negative
-2*28 = -56
one could expect the glacier to have retreated about -56 feet after 28 days since it is no longer moving forward
