2.998 x 10^8 m / s x 60 s / m x 60 m /h x 24 h /d x 365 d / year Multiply those numbers to get m/year

OpenStudy (anonymous):

So you multiply those numbers in order to cancel out the seconds, right?

OpenStudy (anonymous):

yes, to change from seconds to years

OpenStudy (anonymous):

Alright :) Thanks! What about hte other two? :[

OpenStudy (anonymous):

Take your new answer and divide by 1.5 x 10^8 to get how many AU's in a light year.
