An oceanic depth-sounding vessel surveys the ocean bottom with ultrasonic waves that travel 1530 m/s in seawater.

How deep is the water directly below the vessel if the time delay of the echo to the ocean floor and back is 7 s?

Answer in units of m.

    h = Vs*t/2 = 1530*3.5 = 5355 m

    7s there and back.

    3.5s there

    Sound travels at 1530m/s.

    You know the time, I’m sure you can find the distance.

      Are you saying that given the velocity and the time that you can't find the distance?
