🔍 Key Concepts

• Relationship between Local Mean Time (LMT) and Greenwich Mean Time (GMT/UT) • How to convert longitude in degrees to time using 4 minutes per degree • Which time scale the Nautical Almanac uses for entering daily pages for the Sun

💭 Think About

• First, convert 70°30'E of longitude into time. How many hours and minutes does that represent at 4 minutes per degree? • Next, decide whether you add or subtract this longitude-in-time from LMT to get Greenwich time for an east longitude. • Once you have the Greenwich time, look at the choices and pick the one that matches your converted time.

✅ Before You Answer

• Be sure you convert 30 minutes of arc to the correct fraction of a degree before turning it into time. • Double-check the sign rule: In east longitude, does Greenwich time come earlier or later than local time? • Verify that the time you choose is expressed as Greenwich time, since that is what is used to enter the Nautical Almanac for the Sun.
