If it is 10:00 AM at 90°W, what time is it at 30°E?

If it is 10:00 AM at 90°W, what time is it at 30°E?

Step 1: Identify the starting time and location. It is 10:00 AM at 90°W.
Step 2: Identify the target location. We want to find the time at 30°E.
Step 3: Calculate the total distance in degrees between 90°W and 30°E. This is done by adding the absolute values: 90° + 30° = 120°.
Step 4: Determine the time difference for each degree. Each degree of longitude corresponds to 4 minutes of time difference.
Step 5: Calculate the total time difference by multiplying the total degrees by the time per degree: 120° * 4 minutes = 480 minutes.
Step 6: Convert the time difference from minutes to hours. 480 minutes is equal to 8 hours.
Step 7: Add the time difference to the starting time. 10:00 AM + 8 hours = 6:00 PM.
