a unit nto measure space from long distaces
1 light-hour = 1.07925285 × 109 kilometers.
The speed of the light is 3.10^8 miles per second.what is the speed in miles per hour
The distance light travels in an hour. This unit is not used as frequently as the light-year, for example. Distances within the solar system might be expressed in light-hours, but another unit - the astronomical unit - is more commonly used.
Light travels at a speed of 186,000 miles per second or 669,600,000 miles per hour. Light travels somewhat slower when it is "in" something, such as glass or water.

A light hour is the distance light travels in one hour in vacuum. One light hour equals 1.079*10^12 meters.
1 light-hour is 1,079,252,850km
1 hour = 60 minutes.
It takes light exactly one hour to travel in 1 hour.
1 light-hour = 1.07925285 × 109 kilometers.
How far does light travel in one hour
The speed of light is 1,079,252,848.8 kilometers per hour.
1,079,252,850km per light-hour.
The Bright Light Social Hour was created in 2005.
The speed of light in a vacuum is approximately 670,616,629 miles per hour.
"Light-year" is not a speed, it is a distance - the distance light travels in a year.The speed of light is 300,000 kilometers per second. If you multiply that by 3600 (seconds/hour), you get the speed in km/hour.
The speed of light is 670,616,628.6 miles per hour (mph).
