Q

What is the equivalent of 47 min. 20 sec. in arc units?

🔍 Key Concepts

• Relationship between time and arc (longitude) in navigation (24 hours ↔ 360°) • How many degrees of arc the Earth rotates in 1 hour, 1 minute, and 1 second of time • Converting from minutes and seconds of time into minutes of arc step by step

💭 Think About

• First, convert 47 minutes 20 seconds of time into a single unit (either all in seconds or all in minutes). Which is easier for you? • Figure out how many minutes of arc correspond to 1 minute of time. Then multiply to find the total arc for 47 minutes 20 seconds. • Once you have the total arc in minutes of arc, convert that total into degrees and minutes of arc to match the answer choices.

✅ Before You Answer

• Be sure you are using the correct basic rate: 360° in 24 hours of time • Confirm your intermediate values for: degrees per hour, minutes of arc per minute of time, and minutes of arc per second of time before multiplying • After converting to total minutes of arc, carefully divide by 60 to separate degrees and remaining minutes, checking that no rounding is needed
