Assuming the numbers are all in feet, you should be able to determine, from the rules of contour lines, Which hill is higher. Which hill is steeper. What the contour interval is. What the height of each hill is, within an accuracy of 10 ft. The maximum relief of the area, within an accuracy of 20 ft.
Maximum relief is the height difference between the highest and lowest points on a map.
All points on a contour line are at the same elevation. Contour lines are drawn at uniform vertical intervals, called the contour interval. Each contour line has an altitude which is a multiple of the contour interval. Contour lines do not cross, except at overhangs, which are rarely mapped. Contour lines may meet only at a vertical cliff.
