A WOMAN LIVING ON LONGITUDE 30°E IS CARRYING HER BODY TO THE HOSPITAL AROUND 1 AM ON MONDAY. CALLING HER HUSBAND ON PLANE WHO IS ON 30°W, WHEN WILL THE HUSBAND PICK THE CALL

• A. 3 am
• B. 5 pm
• C. 7 am
• D. 9 pm ✓

The answer to the question is: D. 9 pm

To calculate the time when the husband will pick up the call, we need to consider the time difference between the two longitudes and the direction of travel.

Longitude is a geographic coordinate that specifies the east-west position of a point on the Earth’s surface. The Earth is divided into 360 degrees of longitude, with 180 degrees being east and 180 degrees being west. Each degree of longitude represents a time difference of four minutes. Therefore, for every 15 degrees of longitude, there is a one-hour time difference.

In this case, the woman is at Longitude 30°E and is traveling eastward to reach the hospital. Her husband is at Longitude 30°W. Since they are both at the same longitude but on opposite sides of the Prime Meridian (0°), they are 60 degrees apart (30°E – (-30°W) = 60°).

This means there is a time difference of four hours between them.

Given that the woman is calling her husband at 1 am on Monday from Longitude 30°E, it would be 9 pm on Sunday at Longitude 30°W.
