What is the equivalent of 23 min. 20 sec. in arc units?
AI Explanation
The correct answer is D) 5°50'.
To convert 23 minutes and 20 seconds to arc units, we need to divide the time value by 4 (since 1 hour = 60 minutes = 240 degrees).
23 minutes and 20 seconds is equal to 23.33 minutes, which when divided by 4 equals 5.83 degrees, or approximately 5°50'.
The other options are incorrect because:
A) 16°40' is too large
B) 12°32' is too large
C) 9°28' is too large
