How can you prove how fast sound is?

To get a quick estimate, you can watch an event that is a few hundred meters away - for example, somebody chopping wood with an axe, or doing something else that produces a clear sound. Measure or estimate the distance, and estimate the time it takes from the moment you see the axe strike the wood, and the moment you hear it. Divide the distance by the time. Note: We are assuming that the speed of light is very fast, compared to the speed of sound.
