a. Solve this equation for h.

I got (D^2)/1.44) = h

Is that correct?

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? Can you see Cheyenne, Wyoming (about 89 miles away)?

This is my set up:

D = 1.2(sqrt{14,255})

Do I solve for D and then compare my answer to 89 miles?
