Question 58183
An airplane covered 20 miles of its route while decreasing its altitude by 34,000 feet.  Find the slope of the airplane's line of descent.  Round to the nearest hundredth.  [Hint: 1 mi = 5280 feet.]
--------------------------
slope = -34000/5280 = -6.439 
This means for every foot he goes forward he decends 6.39 ft.
