I wanted to know how long the light from the sun traveled.

December 20, 2008

I came up with this…and yes I know I can just put in google, but that would be far too easy.

299,792,458 mps / 1600 = 117.10642890625 mps x 60 = 7026.385734375 mph

earth distance from sun: 94.5 million (max)/91 million (minium)/92.58 million (average)

Distance(mi)    Speed(mph)                  time light travels from sun to surface of earth.
Maxium : 94,500,000 / 7026.385734375 =  7.4353288194444444444444444444444e-5 seconds
Minium : 91,000,000 / 7026.385734375 =  7.7213030048076923076923076923077e-5 seconds
Average: 92,580,000 / 7026.385734375 =  7.5895287690375891121192482177576e-5 seconds

What did I do wrong, it seems that the distance that is further should be the larger time, but its shorter than the other times.

Mr. Cooke, a bit of help please?

  1. You converted meter per second to miles per hour but never converted back to seconds.

    So, Let’s just convert what we need:
    The speed of light is approximately 299792458 meters per second. 1 mile is equal to approximately 1609.344 meters.

    Therefore: 299792458 / 1609.344 = 186282.4 miles per second

    That makes your calculations:
    Maximum : 94,500,000 / 186282.4 = 507 seconds
    Minimum : 91,000,000 / 186282.4 = 489 seconds
    Average: 92,580,000 / 186282.4 = 497 seconds

    and there are 60 seconds in a minute:
    507 / 60 = 8.45 minutes = 8 minutes 27 seconds
    489 / 60 = 8.15 = 8 minutes 9 seconds
    497 / 60 = 8.283 = 8 minutes 17 seconds


  2. You also misspelled my name, the word minimum and the word maximum.


  3. Ah, oops. That makes sense now. And I blame the California School systems for the typos, you can take it up with them. I will however fix your name.
