Exercise about time and lightyears
Spaceship speed = 200km/h, lightyears to travel = 5. Years it will take to travel = 27000000. I cant figure out how to find how many years itll take to travel, I tried converting lightyears to km and so, but no good. Thank you.

speed = 200 km/h
c = 3e+8 m/s
s * 3600 * 24 * 365.2425 = y
ly = m/s * secs/year
4 ly = 4 * 3e+8 m/s * 3600 * 24 * 365.2425 = 4.77e+16 m
4.77e+16 m / 2e+5 m/h = 2.385e+11 h = 27.2 My

Thank you for your answer helios, but its quite hard to understand it. Could you please add a little more detail please ? Also, forgot to mention, every year is supposed to be 365 days. Thank you. Keskiverto, 1 lightyear according to wiki is 9 460 730 472 580, 8 km, but I dont think I need to use that number in calculations.
