Looking at Flightaware, typical durations are between 10:30 and 10:45. It also shows the great circle distance as 9,086km, or 5,645 statute miles. That makes an average speed of 535 mph, quite subsonic.

Of course, ground speed and airspeed are not the same things. The Mach number is airspeed, and if there is a tailwind then the ground speed will be higher.
