The LMT of sunrise on the standard meridian is 0552. Your longitude is 99°15'E. What is your ZT of sunrise?
AI Explanation
The correct answer is D) 0615.
To determine the ZT (Zone Time) of sunrise, we need to convert the LMT (Local Mean Time) of sunrise to the ZT based on the longitude. Since the given longitude is 99°15'E, the time zone difference is +6 hours (4 minutes per degree of longitude east of the standard meridian). Therefore, the ZT of sunrise is the LMT of sunrise (0552) plus 6 hours, which is 0615.
The other options are incorrect because they do not account for the time zone difference. Option A (0512) is 40 minutes earlier than the correct ZT, Option B (0529) is 46 minutes earlier, and Option C (0552) is the LMT of sunrise, not the ZT.
