To find out which planet has the fastest moon with a speed of 113,300 km/h, we can start by examining the known moons of each planet in our solar system.

First, let's look at some of the largest and most well-known moons in our solar system:

- Earth: Earth's moon (Luna) orbits at an average speed of about 3,600 km/h, so it's not the correct answer.
- Mars: Mars has two small moons, Phobos and Deimos. Phobos orbits at a speed of about 2,100 km/h and Deimos at about 1,230 km/h, so Mars is not the planet we're looking for.
- Jupiter: Jupiter has many moons, including four large ones known as the Galilean moons (Io, Europa, Ganymede, and Callisto). Among these, the moon with the highest recorded speed is Io, which orbits at a speed of about 61,700 km/h. Therefore, Jupiter is not the planet we're looking for.
- Saturn: Saturn has numerous moons as well, but none of them have speeds close to 113,300 km/h. Thus, Saturn is not the answer.

So far, none of the planets we've examined have a moon with the given speed. However, there is one more planet we can check:

- Uranus: Uranus is known to have 27 moons, and among them, the moon Miranda has been recorded to have speeds of up to 113,300 km/h, making it the fastest moon in our solar system. Hence, the answer to your question is Uranus.

Remember that our knowledge about celestial bodies is continually expanding, and there may be new discoveries in the future that could change our understanding.
