On 9 February your 0830 zone time DR position is LAT 22°19.0'N, LONG 64°37.0'E. Your vessel is on course 128°T at a speed of 19.0 knots. What is the zone time of local apparent noon?

Correct Answer: Option A — 1152

Calculate vessel's DR position longitude at LAN by running dead reckoning forward. Convert longitude difference in time (Long/15) and apply it to Greenwich Mean Time of LAN from the Nautical Almanac, adjusted for zone description, yielding 1152 zone time.
