Answer: An object moving with a speed greater than the speed of sound is said to have supersonic speed. Supersonic travel is a rate of travel of an object that exceeds the speed of sound
Explanation:
Supersonic travel 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 m/s, 1,125 ft/s, 768 mph, 667 knots, or1,235 km/h.
