Question

11.15 - Using the figure below, calculate how far from A, along the line from A to EB to the contour line for the value 250, if the distance shown das is 148 units Provide the corresponding distances for the additional points/distances How far from B is the 300 contour on a line from B to D, if the distance dno is 94 units? How far from E is the 250 contour on a line from E to D, if the distance deo is 115 units? How far from C is the 200 contour on a line from C to D, if the distance dco is 188 units? How far from E is the 300 contour on a line from E to G, if the distance deo is 248 units? A.210 dAB 18,260 F,420 distance A to contour volue 250 1184 148.250-210) (260 210) D.310 C.180 G,340 E.220

Explanation / Answer

1) For A to B it is already solved.

same formula can be applied for others

2) 94 x ((300-260)/(310-260))

=75.2 units

3) 115x ((250-220)/(310-220))

= 38.33 units

4) 188x ((200-180)/(310-180))

= 28.92 units

5) 248x ((300-220)/(340-220))

= 165.33 units
