At the coordinates 45 degrees W & 72 degrees N it is 9:32 AM. What time is it at the coordinates 75 degrees W & 45 degrees S? 8:32 AM, 10:32 AM, 11:32 AM, 7:32 AM

The correct option is;

7:32 AM

Explanation:

The information given are;

The time at 45 degrees W and 72 degrees N = 9:32 AM

The variation of time with lines of longitude  is given as 15 degrees for each 1 hour variation, therefore, where we have the other location at 75 degrees W and 45 degrees S, the difference in the longitude = 75 - 45 = 30 degrees west  of the initial location

Moving west is in the opposite direction of the Earths rotation, therefore, we subtract 1 hour for every 15 degrees giving 30/15 = 2 hours subtracted

The time at 75 degrees W and 45 degrees S is therefore, 9:32 AM - 2 hour = 7.32 AM

The latitude of a place left out in the calculation of the relative time of a place.
