Convert one light year to miles per year?

Question

speed of light=3.00*10^8 m/s
1km=.6214 miles
assume there are 365 days in one year

I need someone to actually work it out because I tried it but i got it wrong so I need to know which step did I mess up.

Answer 1

According to wikipedia, one light year equals;
about 5,879,000,000,000 statute miles, or
9,460,730,472,580.8 km

Answer 2

if the speed of light =3.00*10^8 m/s
then you will need to divide that by 1000 to get kilometers per second
then use the formula 1km = .6214 to convert it to miles
then multiply that by 60 to make it a minute
then by 60 again to make it a hour
then by 24 to make it a day
then by 365 to make for a year
you do the math !!!!

Answer 3

Can't be done. A light year is a measure of distance, not velocity.
The speed of light in miles per year is about
(3.00*10^8 m/s)(0.6214 mi/km)(3,600 s/h)(24 h/d)(365 d/y) = 5.87894112*10^15 mi/yr

edit:
which, incidentally, is 1 light year per year

Answer 4

3*10^8 m/s * 621.4 miles/m * 60 s/min * 60 min/hr * 24 hr/day * 365 day/year = 5.87894112*10^18 miles/year

Answer 5

A light year is a measure of distance, so it's not "miles per year". Its just miles, or kilometers.

Answer 6

you already have miles per second

so, how many seconds in a year

think

then you multiply the seconds by the travel for 1 second

Answer 7

5.878x10^12
beat that hot shot

Answer 8

it's about one trillion miles
