Q

What is the equivalent of 10? 48' in time units?

🔍 Key Concepts

• Relationship between arc degrees and time on the Earth (24 hours = 360° of longitude) • Conversion of degrees and minutes of arc into hours, minutes, and seconds of time • How to handle the 48' (minutes of arc) portion separately from the whole degrees

💭 Think About

• First convert 10° of arc into time: how many hours or minutes of time correspond to 15° of longitude? Use that to scale to 10°. • Then convert 48' of arc into a fraction of a degree, and turn that fraction into time (minutes and seconds). • Finally, add the time from the whole degrees and the time from the minutes of arc, and compare with the choices.

✅ Before You Answer

• Remember that 15° of longitude = 1 hour of time; set up a proportion from that fact. • Convert 48' to degrees before turning it into time, or directly set up a proportion using 60' = 1°. • After your calculations, make sure your final result is in minutes and seconds of time and matches one of the options.
