    Answer:

    360m/s

    Step-by-step explanation:

    In the question, it is given that the distance traveled by sound is 2×90= 180m

    as it is a reflected or echo sound. We know that time taken is the inverse of frequency.

    Hence, the time taken is calculated as follows.

    T= 1/2=0.5seconds

    d=vt/2

    v=180/0.5

    = 360m/s
