Supersonic speed - Wikipedia, the free encyclopedia Supersonic speed is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343.2 m/s, 1,125 ft/s, 768 mph, 667 knots, or 1,235 km

supersonic flight -- Encyclopedia Britannica supersonic flight, passage through the air at speed greater than the local velocity of sound. The speed of sound (Mach 1) varies with atmospheric pressure and temperature: in air at a temperature of 15 C (59 F) and sea-level pressure, sound travels at abo
