Q

What is the equivalent of 37 min. 32 sec. in arc units?

🔍 Key Concepts

• Relationship between time and arc in celestial navigation (15° per hour of time) • Conversion steps: hours ↔ degrees, minutes of time ↔ minutes of arc, seconds of time ↔ minutes of arc • How to correctly handle seconds of time when converting to arc

💭 Think About

• First, convert 37 min 32 sec of time into a decimal number of hours. What do you divide by? • Once you have hours, multiply by 15 to get degrees of arc. What does that give you in decimal degrees? • Finally, convert the decimal part of the degrees into minutes of arc. Does this match any of the options when rounded properly?

✅ Before You Answer

• Be sure you are using 15° of arc per hour of time (not per minute). • Convert seconds of time to a fraction of a minute, and then to a fraction of an hour before multiplying. • After getting decimal degrees, carefully convert the fractional degree to minutes of arc and compare with the answer choices.
