A place located at 75°W is how many hours behind GMT?

Step 1: Understand that the Earth is divided into 360 degrees of longitude.
Step 2: Know that each 15 degrees of longitude corresponds to 1 hour of time difference from GMT (Greenwich Mean Time).
Step 3: Identify the location in question, which is at 75°W (75 degrees West).
Step 4: Calculate how many 15-degree segments fit into 75 degrees by dividing 75 by 15.
Step 5: Perform the calculation: 75 ÷ 15 = 5.
Step 6: Conclude that a place at 75°W is 5 hours behind GMT.
