Question 1477Navigation General

The correct answer is C) 2040 miles. At upper transit, if the zenith distance is 34°, the geographical distance from the observer to the body's GP (Geographical Position) is 2040 miles. This is calculated using the formula: geographical distance = 60 x (90° - zenith distance). Since the zenith distance is 34°, plugging this into the formula gives 60 x (90° - 34°) = 60 x 56° = 2040 miles. The other options are incorrect because they do not match the calculated value of 2040 miles based on the given zenith distance of 34°.
