15 degrees equals 1 hour. This is derived from the fact that the Earth rotates 360 degrees in 24 hours. So, dividing 360 degrees by 24 hours gives you 15 degrees per hour. This applies in contexts like astronomy and celestial navigation, aiding in calculations related to the Earth's rotation and timekeeping.
FAQs & Answers
- Why does the Earth rotate 15 degrees in one hour? The Earth completes a 360-degree rotation in 24 hours, so dividing 360 by 24 gives 15 degrees per hour.
- How is the 15 degrees per hour used in navigation? Navigators use the 15 degrees per hour rotation rate to calculate longitude and track celestial bodies relative to time.
- What is the relationship between Earth's rotation and time zones? Each time zone generally spans 15 degrees of longitude, corresponding to one hour of Earth’s rotation.
