You can speak in terms of 'travel' in general if you haven't yet identified your mode of transport. Otherwise you can replace 'travel' with: taxi, bus, car etc

We use the words "cost/average cost" to talk about how much it would be for something. "How much would it cost me to get from San Francisco to New York?" What's the average cost of a plane ticket from New Jersey to Las Vegas?"

Hypothetically speaking: means just to know for information. It doesn't mean that you plan to go by taxi but IF you were going to go, you want to know how much it costs. It centers around "If", a situation that isn't real. It is used a lot with American culture and can be used in a lot of different situations. Fare: means cost and is associated with public transport. Like bus fare, train fare, and taxi fare. Hope this helps.
