If an event that starts at 11:00 am at station X appears on the screen at 5.00 am (same day) at station Z, the longitudinal difference between the two stations is?

Answer Details

To calculate the longitudinal difference between the two stations, we need to know the time difference between the two stations when the event occurs. Since station Z is ahead of station X in terms of time, we can calculate the time difference by subtracting the start time of the event (11:00 am) at station X from the time it appears on the screen at station Z (5.00 am). 5.00 am minus 11.00 am gives us a time difference of 6 hours. To convert this time difference to a longitudinal difference, we need to know that the Earth rotates 360 degrees in 24 hours. Therefore, the Earth rotates 15 degrees per hour (360/24=15). Multiplying 6 hours by 15 degrees per hour, we get a longitudinal difference of 90 degrees between the two stations. Therefore, the answer is option B) 90°.
