How should longitude 116°24.3'W be written when preparing an AMVER report?

Correct Answer: Option D — 11624W

AMVER reporting standards dictate that longitude must be formatted as a five-digit group (three digits for degrees, two for minutes) followed by the hemisphere designator. Rounding 116°24.3'W to the nearest whole minute yields 11624W, ensuring compatibility with the automated tracking system.
