70% to pass

The equation of time is 8m 00s. The mean Sun is ahead of the apparent Sun. If you are 2°W of the central meridian of your time zone, when will the apparent Sun cross your meridian?

A 1152
B 1208
C 1216
D 1200
AI Explanation

The correct answer is C) 1216. The equation of time is 8m 00s, and the mean Sun is ahead of the apparent Sun. This means the apparent Sun will cross your meridian (2°W of the central meridian) 8 minutes later than the mean Sun. Since the mean Sun crosses the central meridian at 1200, the apparent Sun will cross your meridian (2°W) at 1216, which is 8 minutes later. The other options are incorrect because they do not accurately account for the 8-minute offset between the mean Sun and the apparent Sun crossing your meridian.
