The latitude of someone in the United States who sees the Sun at an altitude of 67.5° would be approximately 22.5°. This is because the Sun’s highest altitude in the sky occurs at noon, when it is directly overhead at the Tropic of Cancer, which is located at 23.5°N. So, if someone sees the Sun at an altitude of 67.5°, they would be located about 22.5° north of the equator.
