    0.0875 sec

    Explanation:

    Using the relationship to calculate the time that elapse 2x = vt

    x = distance between the source and the reflector

    v is the velocity of sound in air

    t = time elapsed

    Given x = 30.0m and v = 343m/s

    substituting the values into the formula above to get the total time elapsed t;

    t = 2x/v

    t = 2 (30) / 343

    t = 60/343

    t = 0.175sec

    If you are seated in the middle row, the time that will elapse between the sound from the stage reaching your ear directly will be;

    0.175/2 = 0.0875 secs
