What is the speed of light in air in miles per second?

With an exhaustive internet search lasting literally seconds, I found that the refractive indexof air at sea level is 1.000293 . That was just what I was looking for. It tells us that the speedof light in sea-level air is (speed of light in vacuum) / (1.000293) .(186,282.397) / (1.000293) = 186,227.8 miles per second .
