Question 774891
If you are looking at the horizon, you can determine the distance you are from the horizon in miles, D, from a height, h, in feet by the equation of D = 1.2 sqrt H .
 If you are standing on a mountain top that is 12,000 feet in elevation, how far are you from the horizon?
:
D = {{{1.2*sqrt(12000)}}}
D = 1.2 * 109.5445
D = 131.453 miles
