The figure shows a topographic map. Stacey is at position S and Amy is at position A. Travis, a third hiker, is at position T. If the distance between A and 7 on the map in the figure is 0.50 inch, find each of the following. Assume contour interval = 40 ft and 1 inch = 1600 ft. (Round your answers to the nearest whole number.) 1546 1200 1009 (a) the horizontal distance between Amy and Travis ft (b) the difference in elevation between Amy and Travis ft (c) the angle of elevation from Travis and Amy
