Q

What is the equivalent of 4°36' in time units?

🔍 Key Concepts

• Relationship between degrees of arc and time of rotation on the Earth (360° = 24 hours) • How many minutes of time correspond to 1° of arc on the equator or celestial sphere • How to convert the minutes of arc (') part into seconds of time

💭 Think About

• First, work out how many minutes of time correspond to 1° of arc. Then multiply by 4 to account for the 4 degrees in 4°36'. • Separately convert the remaining 36' of arc into time units (think: what is 1' of arc equal to in seconds of time?). • Add the time for the 4° and the time for the 36' together, then compare with the choices given.

✅ Before You Answer

• Be sure you are using the correct base ratio: 360° = 24h, and reduce that to a simple degrees-to-minutes-of-time rule. • Double-check that you have converted 36' of arc into time using the same ratio, not treating it as 36 minutes of time directly. • Confirm that your final result is expressed in minutes and seconds of time, and then match that exactly to one of the options.
