Question

1. on the left - hand side of the profile graph, label a vertical scale showing 160 feet per inch. if labeled correctly, this profile has a vertical exaggeration of 12.5x. **hint: an elevation of 300 feet is already labeled for you. using a ruler, measure 1 inch down from that point and label it with an elevation that is 160 feet less than 300 feet. label every other line on the profile with the correct elevation.

Explanation:

1. Start with the given 300 ft label.
2. Measure 1 inch down from this point; calculate the new elevation as $300 - 160 = 140$ feet, then label this line 140 ft.
3. Measure another 1 inch down from the 140 ft line; calculate $140 - 160 = -20$ feet, label this line -20 ft.
4. Measure 1 inch up from the 300 ft line; calculate $300 + 160 = 460$ feet, label this line 460 ft.
5. Repeat this process for all remaining vertical lines on the profile, adding/subtracting 160 ft for each inch of distance from the 300 ft reference.

Answer:

• 1 inch above 300 ft: 460 ft
• Given reference line: 300 ft
• 1 inch below 300 ft: 140 ft
• 2 inches below 300 ft: -20 ft

(Continue scaling up/down in 160 ft increments per inch for all remaining vertical lines on the profile)
