.

            = 1.2E+11 years.

It is about 24 times as long as the Sun does exist as a star.

And about 27 times as long as the Earth does exist as a planet.

It is so long, that at the end of this travel / (journey), the Sun will just burn completely and will go out.

It is so long, that you have more than enough time to complete all your deals in this world.

Me too.

5.6 × 10^19/ 5.3*10^4
= 5.6*10^15/5.3
=1.056*10^15
=1.1*10^15

, speed
, distance

Time in hours:

The question asked for YEARS.
You do that and if you want use these for the time units conversion:
24 hours per day
7 days per week
52 weeks per year

Other computation ways are possible.
