Sorry random question one I will soon give you the answer too. I am cleaning out my desk and I found an old crumpled paper assignment from 2 semesters ago. It was from astrology class...
Note: my notes might not make sense to you....
60(6x10^1) seconds in a minute
60(6x10^1) minutes in a hour
3.6 x 10^3 seconds per hour
(3x10^5 km/s) x ( 3.6 X10^3 (something I can't make out)= (1.08 x 10^9 km/h)
(2.4x10^1)hours in a day
(3.65x10^2)days in a year
24x365=8760 ...round it
(1.08x10^9km/h)x(8.77x10^3 h/year) = 9.46 x 10^12 km/y
soooooooooo in long version
9471600000000 km in a year.
phew.....glad I don't have to take that class again....
now i'm throwing that piece of paper away.....
