Respuesta :

Air Mile = 6,080 feet
Normal Mile = 5,280

Normal miles from San Fran - Austin = 1,758.7 

so therefore  i think it would end up being 1,527.3

because 1,758.7 x 5280 = 9,285,936
divide that by 6,080 and you get 1,527.29 which you can round up to 1,527.3
1498.78 Air Miles. I hope this helps.
