🔍 Key Concepts

• Relationship between time and arc in nautical astronomy (15° per hour of time) • Conversion steps: hours ↔ minutes ↔ seconds, then to degrees ↔ minutes of arc • How to handle partial minutes of time when changing to arc units

💭 Think About

• First, convert 8 minutes 56 seconds of time into a single unit (either all minutes of time or all seconds of time). What value do you get? • How many degrees of arc correspond to 1 hour, 1 minute, and 1 second of time if the Earth rotates 15° per hour? • After converting to degrees of arc, how do you change decimal degrees into degrees and minutes of arc, and which answer choice matches that?

✅ Before You Answer

• Be sure you are using time units to arc units (not distance), based on 15° per hour of time. • Check that you correctly handled 56 seconds of time when converting (don’t round too early). • Confirm that your final value is expressed as degrees and minutes of arc (no seconds of arc in any answer choice).
