A tuning for vibrating at frequency 800 Hz produces resonance in a resonance tube. The upper end is open, and the lower end is closed by the water surface, which can be varied. Successive resonance are observed at length 9.75 cm,31.25 cm and 52.75 cm. The speed (in m/s) of sound in air from these data is _____.
