Forever, unless you have an amphibicar; there is no land route from Paris to Chicago.
With Air Tahiti Nui (highly recommended) Paris - Los Angeles - Papeete; 22h30min outward, 21h15min homeward
about 9 hours

"How long is the travel time from laos angeles and California by road?" There is not sufficient information given above to answer the question. Firstly, I assume you meant "Los Angeles", since you also cited California in your question. Alright then, you want to know travel time by road from Los Angeles to ... where? Your question lacks a destination, a point on the map to travel to before the time it takes to get there can be determined.
A direct flight from Paris, France --> Glasgow, Scotland would take about 2 hours.
It takes 5 hrs. And 55min.
