    Answer: The corridor is 82.825 meters long

    Explanation:

    Hi, to answer this question we have to apply the next formula:

    d = (t×c)/2  

    Where:

    Speed of sound c = 331.3 m/s at 0°C  

    t = time = 0.5 s.  

    d = distance

    Replacing with the values given:

    d = (Δt×c)/2 = 0.5×331.3/2 = 82.825 m  

    The corridor is 82.825 meters long

    Feel free to ask for more if needed or if you did not understand something.
