Well - someone else on here asking the same question, got the answer "the speed of light" - but the speed of light in km/h is 1,072,984,320
Wikipedia gives 1079 million kph, but the answer remains vaid.

Nothing in the known universe - since the speed of light is 1080 million kilometres per hour !
Nothing does. That speed is 3.5% greater than the speed of light.
Speed of light. * * * * * Nothing, since the speed of light in vacuum is around 1080 million km/h.
Nothing can travel faster than the speed of light which is 1080 million kms per hour. ( 300 x 106 metres per second)
Nothing, since the speed of light in vacuum is around 1080 million km/h. ======================================== The caveat "approx" can absorb a lot of flab. The number is about 3.5% above the speed of light. Within the definition of "approx", perhaps 'c' is what the questioner is fishing for.
Speed of light * * * * * Nothing, since the speed of light in vacuum is around 1080 million km/h. In any case, the "speed of light" does not travel!
A fighter jet.
Speed of light
Expressed in kilometres per hour, this is equal to 300/6 = 50 kilometres per hour.
If it travels x kilometres in 1 hour, it is travelling at x km/h.
