In the air, Mach 1 decreases with altitude from roughly 760 mph (340 m/s) at sea level and 15 'C to about 660 mph (295 m/s) at 36,000 feet to 66,000 feet (11 000 m to 20 000 m) and -57 'C (cruising altitude of commercial jets).
So 0.85 times that amount gives Mach 0.85 ranging from 646 mph to 560 mph.
Mach 0.85 = about 630.3 mph
