CNAV Time Question
Tayler.firstname.lastname@example.org created the topic: CNAV Time Question
Just a quick question regarding the CNAV progress test question 16 on page 48:
"the time taken for the the sun to cross two consecutive meridians is closest to?"
The answer states (b) 4 minutes
My confusion is where it states 'two consecutive meridians', so to me it's saying two meridians, and from my understanding each meridian is one degree. So if each degree equates to 4 minutes of time, I would have thought the answer would be 8 minutes.
Can anyone point me in the right direction, because I'm assuming my understanding of the material is off and I'm self studying all this at home, so it's hard to get advice and make sense of certain things.
Interesting interpretation Tayler. However a meridian is just a line on the earth's surface and each meridian is separated from its neighbour by 4 minutes of time. So for the sun to cross two consecutive meridians it must travel the distance that separates the two lines. That takes 4 minutes. It would take 8 minutes for the sun to cross three consecutive meridians.
