THE BEST WAY TO SOLVE THIS IS TO SET UP A GRAPH. ASSIGN THE POINT (0,1800)FOT YHR TOP OF THE MOUNTAIN.
NOW SET A SECOND POINT (5280*3.25,0) FOR THE END OF THE DESCENT DOWN THE MOUNTAIN.
THESE 2 POINTS ARE (0,1800) & (17,160,0).
TO FIND THE SLOPE BETWEEN THESE TWO POINTS WE USE (Y2-Y1)/X2-X1) OR
(0-1800)/(17,160-0)
-1800/17,160=.104895 OR -.1 IS THE SLOPE OF THIS DESCENT.
