What must be the actual time when the Sun is exactly right above our heads?
Consider the following assumptions.
- The distance between the Sun and the Earth is 8 minutes 20 seconds in time scale on an average.
- You are at the nearest point to the Sun on the surface of the Earth.
- Earth has no tilt.
- All normal conditions, i.e., 24 hours a day etc.

As we all know, the distance between the Sun & the Earth is approximately 150,000,000 km and also the maximum known speed of light (approximately) is 300,000,000 km/s. Hence, the time the photon takes from the surface of the Sun to that of the Earth is calculated to be an average of 8 min 20 sec...
So, when we feel the Sun's position to be overhead, it means that we are sensing (rather seeing) only the photons that left the Sun past 8 min 20 sec... But on our planet, we consider, the Sun's overhead position as 12:00:00 (HH:MM:SS) noon. Hence, going back to 8 min 20 sec, i.e., 11:51:40 (HH:MM:SS) is the right answer for the given problem, I think.
