Question: If a plane travels from 30°W to 30°E, how many degrees of longitude does it cross?

Options:

Correct Answer: 60°

Solution:

The total distance crossed is |30°W| + |30°E| = 30° + 30° = 60°.

If a plane travels from 30°W to 30°E, how many degrees of longitude does it cross?

If a plane travels from 30°W to 30°E, how many degrees of longitude does it cross?

Step 1: Understand that longitude is measured in degrees east and west of the Prime Meridian, which is at 0°.
Step 2: Identify the starting point, which is 30°W (30 degrees west of the Prime Meridian).
Step 3: Identify the ending point, which is 30°E (30 degrees east of the Prime Meridian).
Step 4: Calculate the total degrees crossed by adding the absolute values of the two longitudes: |30°W| + |30°E|.
Step 5: Perform the addition: 30° + 30° = 60°.
Step 6: Conclude that the plane crosses a total of 60 degrees of longitude.
