How long does it take the Earth to rotate 45 degrees?

The correct response is based on understanding the Earth's rotation and how it correlates with the passage of time. The Earth completes one full rotation of 360 degrees in approximately 24 hours. To determine how long it takes for the Earth to rotate 45 degrees, you can set up a ratio based on these figures.

Since there are 360 degrees in a full rotation, dividing 24 hours by 360 degrees gives you 0.06667 hours per degree. For 45 degrees of rotation, multiplying the time per degree (approximately 0.06667 hours) by 45 results in 3 hours.

This method applies basic concepts of time and degrees of rotation to find the answer, reinforcing the understanding that the Earth rotates continuously and at a consistent rate, which allows for such calculations. This illustrates the importance of understanding the relationship between time and rotational degrees to solve problems related to Earth's movement.
