If a plane travels from a location at 30° West longitude to a location at 60° Ea

If a plane travels from a location at 30° West longitude to a location at 60° East longitude, what is the total angular distance in degrees? (2023)

If a plane travels from a location at 30° West longitude to a location at 60° East longitude, what is the total angular distance in degrees? (2023)

Step 1: Identify the starting longitude, which is 30° West.
Step 2: Identify the ending longitude, which is 60° East.
Step 3: Understand that West longitudes are negative and East longitudes are positive.
Step 4: Calculate the distance from 30° West to the Prime Meridian (0°), which is 30 degrees.
Step 5: Calculate the distance from the Prime Meridian (0°) to 60° East, which is 60 degrees.
Step 6: Add the two distances together: 30 degrees (to the Prime Meridian) + 60 degrees (to 60° East) = 90 degrees.
Step 7: Recognize that 30° West and 60° East are on opposite sides of the Prime Meridian, which means the total angular distance is actually 180 degrees.
