🔍 Key Concepts

• Relationship between time and arc on the celestial sphere (24h of time = 360° of arc) • Conversion factors: 1 hour of time = how many degrees of arc? 1 minute of time = how many minutes of arc? 1 second of time = how many seconds of arc? • Method of converting everything to seconds, then back to degrees and minutes

💭 Think About

• First convert 23 min 20 sec of time into total seconds of time. What number do you get? • Use the fact that 1 second of time corresponds to a fixed number of arc-seconds. Multiply your total time-seconds by this value to get total arc-seconds. • Convert your total arc-seconds back into degrees and minutes of arc. Which choice matches your result?

✅ Before You Answer

• Be sure you are using the time-to-arc ratios (based on 24h = 360°), not distance or speed formulas. • Double-check that you converted both minutes and seconds of time before multiplying; don’t mix time minutes with arc minutes. • After converting to arc, confirm your final value is in degrees and minutes of arc only (no leftover arc-seconds, or account for them properly).
