We know that the speed of light in free space is 299,792,458 meters per second, which works out to 299,792,458/0.3048 = 983,571,056.43 feet per second, or 983,571,056.43/5,280 = 186,282.4 miles per second. The reciprocal of the free space value of the speed of light in feet per second is the time it ...
