Correct answer: D. at x = 22 m

Given: Speed of the source, v_s = 22 m s^ -1 Speed of sound, v = 330 m s^ -1 Distance of listener Q from the origin P , d = 330 m The time taken by the sound to travel from the origin P to the listener Q is: t = (d)/(v) = (330)/(330) = 1 s During this time, the distance traveled by the source along the positive X-axis is: x = v_s × t = 22 × 1 = 22 m Therefore, the source will be located at x = 22 m when the sound emitted from P reaches the listener.
