That depends upon the speed of sound through the medium in which the speed is being measured.
mach = speed ÷ speed_of_sound_there
⇒ speed = mach x speed_of_sound_there
In dry air at 20oC the speed of sound is [approx] 1236 km/h
⇒ speed_of_mach_0.85 = 0.85 x 1236 km/h
≈ 1051 km/h
At 11,000m (where the air temperature is about -50oC) the speed of sound is approx 86% of that in air at 20oC, that is about 1063 km/h
⇒ speed_of_mach_0.85 ≈ 0.85 x 1063 km/h
≈ 904 km/h
