I just flew from MI to AK on a Boeing 757-300. While we were on the Tarmac I occupied myself by reading the safety literature that is found in the pocket of the seat back in front of you. In it they had all of the 757 series planes and the average speed was 528 MPH
The Boeing 747 travels at 0.85 mach or 567 mph.
