    Answer:

    350 m/s

    31°C

    Explanation:

    Speed of sound is given as the product of frequency and wavelength

    S=fw

    Where s represent the speed in m/s, f is frequency and w is wavelength

    Conversion

    Taking 1m to be 100 cm then 35 cm will be 35/100=0.35m

    Substituting 0.35 m for w and 1000 Hz for f then

    S=1000*0.35=350 m/s

    speed of sound (m/s) = 331.5 + 0.60 T(°C)

    350=331.5+0.6T

    T=30.833333333333

    The temperature is approximately 31°C
