i know i have to use v=d/t , i was getting the wrong answer

2. Michele_Laino

I'm sorry, I'm not good with astronomy, since I have studied nuclear physics mainly when I was at university

$$\large c_{est} = \frac{d}{t} =\frac{3 \times 10^{11}}{19 \times 60} = ???$$

@IrishBoy123 what confused me about the question is dont u have to measure the distance from going to coming ? so like take the distance and timising by 2 ?

5. anonymous

what makes this question different?

6. IrishBoy123

**distance from going to coming** that to me does not really have any meaning. this is a simple skit about the fact that light itself has a "finite" speed. so, the amateur astronomers assumed instantaneous light , and worked out something different.!? not sure this helps too much.
