The velocity of sound in air is 49.02
feet per second where is the air temperature in degrees Rankine. Write a function to execute this. If just 1 argument is passed to the function, it is supposed to be the air temperature in degrees Rankine. If, though, two arguments are passed, the 2 arguments would be first an air temperature and then a character 'f' for Fahrenheit or 'c' for Celsius (so this would then have to be converted to Rankine). Note: degrees R = degrees F + 459.67. Degrees F = 9/5 degrees C + 32.
