Question: At which longitude would it be 3:00 PM if it is 12:00 noon at 0° longitude?

Options:

Correct Answer: 135°E

Solution:

3 hours ahead means 3 * 15° = 45°. Therefore, 0° + 45° = 135°E.

At which longitude would it be 3:00 PM if it is 12:00 noon at 0° longitude?

At which longitude would it be 3:00 PM if it is 12:00 noon at 0° longitude?

Step 1: Understand that the Earth is divided into 360 degrees of longitude.
Step 2: Know that the Earth rotates 360 degrees in 24 hours.
Step 3: Calculate how many degrees the Earth rotates in one hour: 360 degrees / 24 hours = 15 degrees per hour.
Step 4: Since it is 3:00 PM and we started at 12:00 noon, we need to find the time difference: 3:00 PM - 12:00 noon = 3 hours.
Step 5: Multiply the time difference by the degrees per hour: 3 hours * 15 degrees/hour = 45 degrees.
Step 6: Since we are looking for the longitude that is ahead of 0° longitude, add 45 degrees to 0°: 0° + 45° = 45°.
Step 7: The final answer is 135°E, which is 45 degrees east of 0° longitude.
