Question 175540
2. The equation [D=1.2 square root of h] gives the distance, D, in miles that a person can see to the horizon from a height, h, in feet. 
a. Solve this equation for h.
D = 1.2sqrt(h)
sqrt(h) = D/1.2
h = [D/1.2]^2

b. Long’s Peak in the Rocky Mountain National Park, is 14,255 feet in elevation. How far can you see to the horizon from the top of Long’s Peak?
D = 1.2sqrt(14255) = 143.27 miles
