Now let's calculate spot elevation B in Figure 9.17. What do we know
in looking at the figure? The slope is 2 percent, and the horizontal
distance between points A and B is 120 feet. Now let's calculate the
elevation for point B:
S = V / H
.02 = V / 120'
V = .02 x 120'
V = 2.40'

Referring to Figure 9.18, we will determine the horizontal
distance between points A and B. What do we know looking at
Figure 9.18? We know the slope, and we can calculate the vertical ele-
vation difference between points A and B. With this information we
can calculate the horizontal distance between points A and B.
S = V / H
S = .03
V = A minus B or 36.5 - 32.2 = 4.3'
