Answer:
directly south
Step-by-step explanation:
Apparent solar noon occurs when the observer's meridian and the sun coincide, which causes the shortest shadow during the day and the sun is at the highest position at solar noon.
During the equinoxes the sun is directly over the Equator. During the June solstice the sun is at the tropic of cancer and during the December solstice the sun is at the Tropic of Capricorn.
As the entirety of North America is above the Tropic of Cancer the sun appears directly south.
