What is the relationship between apparent solar time and mean solar time?
The Earth "day" of exactly 24 hours is the "mean solar day"
"Mean" is basically a scientific way of saying "average". It's called a "solar day " because it's based on the position of the Sun in the sky.
There are natural variations in the length of the solar day because of the Earth's elliptical orbit and axial tilt.
The "mean solar day" averages out the variations that happen during the year.
This makes things much more convenient for everyday life.
"Mean solar time" is based on the "mean solar day".
The "apparent solar day" is the what we actually observe, and its length varies from day to day.
A sundial measures "apparent solar time". We can convert this time to mean solar time by using something called "the equation of time".
Actually, the sundial shows "local apparent solar time".
That's because the time shown by a sundial depends on its exact longitude.
For convenience, mean solar time has time zones (based on longitude).
So, longitude also affects the relationship between these two
measures of time.

Does your sundial match you watch time?
As the Sun moves across the sky (actually, it's the Earth turning), the shadows cast by objects move in the opposite direction. A sundial has a piece called a gnomen, and its shadow moves across marked sections for the hours. Because sundials were invented in the Northern Hemisphere, where the Sun appears in the southern part of the sky most of the year, the shadow moves "clockwise."
What is 1 day 4 hrs 7 min - 6 hrs 20 min?
1 day = 24 hrs, and 1 hr=60 min. Therefore 1 day=1440 min. Therefore 1 day + 4 hrs + 7 min equals 1440 min + 240 min+ 7 min or 1687 minutes. Applying the same principal to the other side of the equation gets us 360 min + 20 min or 380 min. 1687 minutes - 380 minutes = 1307 minutes. This equals 21 hrs 47 min.
How many hours is 128 minutes?
128 minutes equals two hours and eight minutes.
One hour equals 60 minutes, so two hours equals 120 minutes.
