That is approximately the speed of light (c). In metric units it is exactly 299792458 meters per second (299792.458 kilometers per second). Even electrons in atoms travel at approximately the same speed (but always less than speed of light)

### How long would it take to get to Venus traveling at the speed of light?

The distance from Venus to Earth varies depending on the
positions of each planet within their respective orbits, varying
between 38 and 223 million kilometres (see related link).
Light travels at approximately 300000 kilometres per second, so
the time of flight will vary between the following extremes:
Minimum time: (38 x 106 km) / (300000 km/s) = 120 seconds (which
is 2 minutes).
Maximum time: (223 x 106 km) / (300000 km/s) = 740 seconds
(which is 12 minutes).

###### Asked in Algebra, Calculus

### What is the standard speed in miles per hour of the light if a travels at 15000 kilometers per second?

From my understanding the speed of light in metric units is
300,000 kilometres per second. 1 mile = 1.609 kilometres
300,000/1.609 = 186,451.2119 miles Therefore the speed of light in
imperial units is 186,451.2119 miles per second There are 3,600
seconds in 1 hour 186,451.2119*3,600 = 671,224,362.8 miles per hour
So the answer to your question is that light travels at
671,224,362.8 miles per hour.
