Q

What is the equivalent of 10 min. 52 sec. in arc units?

🔍 Key Concepts

• Relationship between time and arc on the Earth for navigational calculations • How many minutes of arc the Earth rotates in 1 minute of time • Converting seconds of time into decimal minutes, then into arc

💭 Think About

• First convert 10 minutes 52 seconds of time into decimal minutes of time. What is that value? • For every 1 minute of time, how many minutes of arc does the Earth rotate? Use that to scale your time value. • After converting to total minutes of arc, can you express the result in degrees and minutes to compare with the choices?

✅ Before You Answer

• Be sure you are using the correct time-to-arc factor (arc per minute of time), not degrees per hour directly. • Carefully convert seconds to decimal minutes before multiplying; don’t round too early. • After finding total minutes of arc, convert to degrees and minutes of arc and check that it matches one of the choices exactly.
