When a large airliner approaches an airport, it begins its descent from about 100 miles away and takes about 20 minutes to descend from an altitude of 36000 feet. Assume that the airliner's distance to the airport is a linear function of the time, t (minutes), since it began its descent.
A) Express as a function of t (minutes). Write your answer in slope-intercept form.
B) Now find the airliner's altitude, A, as a function of the airliner's distance from the airport, d. Write your answer in slope-intercept form.
