If it is 10:00 AM at 90°W, what is the time at 60°E?

If it is 10:00 AM at 90°W, what is the time at 60°E?

Step 1: Identify the starting time and location. The time is 10:00 AM at 90°W.
Step 2: Identify the target location. We want to find the time at 60°E.
Step 3: Calculate the total difference in degrees between the two longitudes. This is 90° (from 90°W to 0°) + 60° (from 0° to 60°E) = 150°.
Step 4: Determine the time difference. Since the Earth rotates 360° in 24 hours, it rotates 15° in 1 hour. So, we divide the total degree difference by 15°: 150° / 15° = 10 hours.
Step 5: Add the time difference to the starting time. Since 60°E is ahead of 90°W, we add 10 hours to 10:00 AM: 10:00 AM + 10 hours = 8:00 PM.
