Question 1784Navigation General

The correct answer is B) The set is 270°, drift 0.25 knot. To determine this, we need to calculate the difference between the fix position and the DR position. Since the fix position is 0.5 mile west of the DR position, the set must be 270° (westward) and the drift must be 0.25 knot to produce a 0.5 mile difference over the 2-hour period. The other options are incorrect because: A) A set of 270° and drift of 1.0 knot would result in a larger displacement than 0.5 mile. C) A set of 270° and drift of 0.5 knot would also result in a larger displacement. D) A set of 090° (eastward) would be in the opposite direction of the observed displacement.
