Best ResponseYou've already chosen the best response.0is how many seconds there, now if light travels 300,000km in 1 second, then light will travel x km in 60*60*24*365 seconds

Best ResponseYou've already chosen the best response.0on that on do i need to multiply the seconds part by 300,000?

Best ResponseYou've already chosen the best response.0so you can multiply a value like (x light years) * ( y km/light year ) and obtain only km, the units, light years, cancel out
