Question: If a plane travels from a location at 30°N, 60°W to 30°N, 60°E, how many degrees of longitude does it cross?
Options:
60°
90°
120°
150°
Correct Answer: 60°
Solution:
The plane crosses from 60°W to 60°E, which is a total of 60° + 60° = 120° of longitude.

Questions & Step-by-Step Solutions
If a plane travels from a location at 30°N, 60°W to 30°N, 60°E, how many degrees of longitude does it cross?
Step 1: Identify the starting longitude, which is 60°W.
Step 2: Identify the ending longitude, which is 60°E.
Step 3: Understand that moving from 60°W to 0° (the Prime Meridian) is 60 degrees.
Step 4: Understand that moving from 0° to 60°E is another 60 degrees.
Step 5: Add the two distances together: 60° (from 60°W to 0°) + 60° (from 0° to 60°E) = 120°.
Step 6: Conclude that the plane crosses a total of 120 degrees of longitude.
