suppose the owner of this bicycle decides to hon on his bike and coast down the hill. If he starts at a point where the elevation is listed as 6500 ft. and coasts down a straight section of road to a point where the elevation is 6000 ft., how many feet will he have traveled? Be careful. this is not simple as it may first appear!
