Final answer:
Without access to Figure 26.10, it is impossible to calculate the exact linear distance between the 1400-ft and 200-ft elevation contours. The question involves interpreting elevation contours on a topographic map, which is a skill in geography.
Step-by-step explanation:
The student's question appears to be about calculating the linear distance between two elevation contours on a topographic map. However, without Figure 26.10, it is not possible to provide an accurate answer. The question involves understanding and interpreting elevation on topographic maps, which falls under the subject of Geography and would likely be encountered at the High School level.
In general, the linear distance between two elevation contours can be measured by using a ruler if the map scale is known, or by counting the number of contour lines that cross the straight line path and multiplying by the contour interval, if the topography is relatively uniform and the path does not zigzag significantly. Unfortunately, without the specific map, we cannot give a numerical answer.
