Question 324453
Do you mean D = 1.2{{{sqrt(h)}}}?

If so, D = distance and h = height

Divide both sides by 1.2.

D/1.2 = {{{sqrt(h)}}}

Square both sides to find h.

(D/1.2)^2 = [{{{sqrt(h)}}}]^2

D^2/1.44 = h

=============================

To find how far a person can see, replace h with 14255 in the original equation and solve for D.

D = 1.2{{{sqrt(14255)}}}

D = 143.27 feet
