Questions & Step-by-Step Solutions
If a plane travels from a location at 60°W to a location at 30°E, what is the total change in longitude? (2023)
Step 1: Identify the starting longitude, which is 60°W.
Step 2: Identify the ending longitude, which is 30°E.
Step 3: Understand that moving from 60°W to 0° (the Prime Meridian) is a change of 60°.
Step 4: From 0°, move to 30°E, which is an additional change of 30°.
Step 5: Add the two changes together: 60° (to reach 0°) + 30° (to reach 30°E) = 90°.
Step 6: Conclude that the total change in longitude is 90°.
