Question

You are standing at the point x = 300 m, y = 400 min a reference frame with synchronized clocks. what time does your clock show at the instant you see the clock at the origin showing 3.00 µ,s?

Answer 1

The point where you're standing ... (300, 400) ... is 500 m from the origin.

Light takes (500 m) / (3 x 10⁸ m/s) = 1.67 μs to travel from the origin to you.

So when you SEE the clock at the origin read 3.0 μs, you're
seeing it as it was 1.67 μs ago.  YOUR clock says 4.67 μs .
