How far does light travel in each time period?
(a) 1.0 s
(b) 1.0 day
(c) 1.0 yr
1.798791×1010m/min=1.798791×107 km/min=1.117886×107mi/min, nearly.
The speed of light in a vacuum in meters per second is
There's 24 hours in a standard day. Each hour has 3600 seconds in it (60 minutes, each of 60 seconds, 60 * 60 = 3600).
So, that means light travels 3600 * 24 * 300 000 km in one 24-hour day, or about 25920000000...
