If the velocity of the solar wind is about 400 km/s and the visible tail of a comet is 10 to the power of 8 km

how long does it take an atom to travel from the nucleus to the end of the visible tail?

Need to know how the solar wind effects that atom and it's starting velocity and vector. Without more data, no significant answer possible unless too much is assumed.

d = v t
0.1 Gm = 0.4 Mm/s x t
t = 0.25 ks = 4.2 min
