Question 1687Navigation General

The correct answer is B) 11°50'. To convert 47 minutes and 20 seconds into arc units, we need to use the conversion factor of 1 degree = 60 minutes. First, we convert the 47 minutes and 20 seconds into decimal minutes: 47 minutes + 20 seconds = 47.33 minutes Then, we can convert the decimal minutes into degrees: 11.33 degrees = 11°50' Therefore, the equivalent of 47 minutes and 20 seconds in arc units is 11°50'. The other options are incorrect because they do not accurately represent the conversion of 47 minutes and 20 seconds into degrees and minutes.
