Although The Guinness Book of Records recorded the XF-84H as the fastest propeller-driven aircraft ever built, with a design top speed of 670 mph (1,080 km/h) (Mach 0.9) and 623 mph (1,003 km/h) (Mach 0.83) during tests, this claim has been disputed.
It depends on the type of plane. Small, one-engine propeller planes (reciprocating engines) fly at speeds of 80 to 200 mph (130 to 320 km/hr). The question can't really be answered...it's like asking how fast does a car go...it all depends on what type of car. Same thing for airplanes...it depends on the type.
