Since the speed of sound through the standard atmosphere is 761 mph (1,223 km/h) at sea level, Mach 2 then follows as 1,522 mph (2,447 km/h). If you were to ask how fast is Mach 2 at an altitude of 30,000 ft (9,150 m), we would use the same methodology to find out that it is only 1,356 mph (2,180 km/h) because the speed of sound generally decreases as altitude increases.
the DARPA âcheetahâ is the worldâs fastest running robot, capable of moving at speeds up to 18mph. engineers of DARPA (the US defense advanced research projects agency) have set a new land speed record for a legged robot with the âcheetahâ, capable of galloping at speeds of up to 18mph.
