Question 1964Navigation General

The correct answer is C) 90°W. The time meridian used when computing the currents for Pensacola Bay, Florida, is 90°W. This is because Pensacola Bay is located in the Central Time Zone of the United States, which is based on the 90th meridian west of Greenwich. The currents in this region are calculated using the time references and tidal information associated with the 90°W time meridian. The other answer choices are incorrect because 60°W is the time meridian for the Atlantic Time Zone, 75°W is the time meridian for the Eastern Time Zone, and 105°W is the time meridian for the Mountain Time Zone, none of which are relevant for the location of Pensacola Bay, Florida.
