Q: If a plane travels from a location at 30 degrees East to a location at 30 degrees West, how many degrees of longitude does it cross?

Solution: The total distance crossed is 30 + 30 = 60 degrees of longitude.

Steps: 6

Step 1: Understand that longitude is measured in degrees east and west of the Prime Meridian, which is at 0 degrees.
Step 2: Identify the starting point, which is at 30 degrees East.
Step 3: Identify the ending point, which is at 30 degrees West.
Step 4: Calculate the total distance crossed by adding the degrees from the starting point to the Prime Meridian (30 degrees) and from the Prime Meridian to the ending point (30 degrees).
Step 5: Add the two distances: 30 degrees (East) + 30 degrees (West) = 60 degrees.
Step 6: Conclude that the plane crosses a total of 60 degrees of longitude.
