If it is 6:00 AM at 30° East longitude, what time is it at 120° West longitude? (2022)

If it is 6:00 AM at 30° East longitude, what time is it at 120° West longitude? (2022)

Step 1: Identify the time at 30° East longitude, which is 6:00 AM.
Step 2: Calculate the total degrees of longitude between 30° East and 120° West. This is done by adding the two longitudes: 30 + 120 = 150 degrees.
Step 3: Determine the time difference in hours. Since the Earth rotates 15 degrees per hour, divide the total degrees by 15: 150 / 15 = 10 hours.
Step 4: Since 120° West is to the west of 30° East, subtract the time difference from 6:00 AM. So, 6:00 AM - 10 hours = 8:00 PM the previous day.
