How far is tennessee from htx?

I'm curious to know, how far exactly is the state of Tennessee located from the abbreviation "htx"? Is this referring to a specific city or area within the United States, and if so, how would one go about calculating the distance between the two locations? Perhaps there's a misunderstanding in the question, as "htx" isn't a commonly recognized abbreviation for a state or city in relation to Tennessee. Could you please clarify the intended destination or provide more context for a more accurate response?
