The sun appears to move about 60 degrees in four hours.
Of course, the sun is not moving, the earth is rotating making it appear to ancient people the sun is moving.
The sun appears to move 15 degrees of longitude each hour if it moves 360 degrees in 24 hours. This is because there are 24 hours in a day, so dividing 360 degrees by 24 hours gives us 15 degrees per hour.
Stars appear to move around Polaris, the North Star, due to the Earth's rotation. In three hours, the Earth rotates approximately 45 degrees (360 degrees in 24 hours). Therefore, stars appear to move about 45 degrees around Polaris during that time.
Once, plus just a little bit more. The Earth actually rotates once in 23 hours 56 minutes. However, during that time the Earth continues to move in its orbit around the Sun, and it takes the Earth another 4 minutes worth of rotation to point back at the Sun again. The 23h 56m "sidereal" day is with reference to the stars, while the 24-hour "solar" day is with reference to the Sun.
As you move east from the Prime Meridian, time increases by one hour for every 15 degrees of longitude you cross. This is because Earth rotates 360 degrees in 24 hours, so each hour represents 15 degrees of longitude.
On June 21, the summer solstice, locations between 66.5 degrees North (the Arctic Circle) and 90 degrees North (the North Pole) experience 24 hours of daylight. This phenomenon occurs because the North Pole is tilted towards the Sun during this time, resulting in continuous sunlight for regions within the Arctic Circle. As you move closer to the Pole, the duration of daylight remains constant at 24 hours.
Through an angle of 60 degrees.
360 divided by 24 equals 15. The sun appears to move 15 degrees each hour, or one degree every four minutes.
90 degrees
150 degrees
45 degrees
45
The sun appears to move 15 degrees of longitude each hour if it moves 360 degrees in 24 hours. This is because there are 24 hours in a day, so dividing 360 degrees by 24 hours gives us 15 degrees per hour.

360 degrees in 12 hours , so 360/12 ie 30 degrees
Stars appear to move around Polaris, the North Star, due to the Earth's rotation. In three hours, the Earth rotates approximately 45 degrees (360 degrees in 24 hours). Therefore, stars appear to move about 45 degrees around Polaris during that time.
It takes twelve hours for the hour hand to move 360 degrees In half an hour the hour hand moves 15 degrees
Each hour, it rotates through 30 degrees, every twelve hours, it rotates 360 degrees.
