A person is standing at the edge of the water and looking out at the ocean (see the drawing). The height of the person’s eyes above the water is h=1.6 m, and the radius of the earth is R=6.38x10^6 m (use as a precise value). (1) How far is it to the horizon (in meters, use two significant figures)? In other words, what is the distance d from the person’s eyes to the horizon? (Note: At the horizon the angle between the line of sight and the radius of the earth is 90°.) (2) Express this distance in miles.
