You're asking how long it takes light and heat to travel from the sun to the earth, but mixing your units.
The "299 ... ...' is the speed of light in meters per second, and the "93 ... ..." is the distance in miles.
The answer is still 8-1/3 minutes.
Light travels at 299792458 meters per second in a vacuum.
The speed of light is approx 299792458 metres per second. And it does not travel any faster nor slower in the US.
93000000/70 is 1328571.43 hours or 55357.14 days or 151.56 years
My vote is: 8minutes 19seconds
299792458 metres per second 299792.458 kilometres per second
1 nautical mile = 1852 meters Speed of light = 299 792 458 m / s Speed of Light = (299792458/1852) nautical miles / second One hour has 60 minutes, each has 60 seconds. 60x60 = 3600 seconds in a hour. In 1 second, light travels 299792458/1852 nautical miles. In 3600 seconds, light travels (299792458/1852)x3600, which is approximately: 582749918,3585 nautical miles / hour
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)
Light travels at 299792458 meters per second in a vacuum.
Distance = velocity * time = 299792458 m / s * 0.000000001 sec = 0.299792458 metres
The speed of light in a vacuum is exactly 299792458 m/s
The SI metre is defined such that the speed of light in a vacuum is exactly 299,792,458 metres per second. This equates to 186,282.4 miles per second.The figure is 186,282 miles (299,793 kilometers) per second
The exact value is 299 792 458 m/s HOWEVER the accepted value used by today's society is 3.00x10^8 m/s
