Question

An oceanic depth-sounding vessel surveys the
ocean bottom with ultrasonic waves that
travel 15360 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 46 s?
Answer in units of m

Answer 1

Assume time down equals time up.

depth=velocitysound*timedown
= 15360m/s * 23sec

Now, because I am so kind and good, I do need to point out that this given sound is incredibly inaccurate, the actual velocity of sound in salt water is around 1560m/s, depending on temperature. In Ice, curiously enough, the speed of sound is about twice as fast.

So I wonder if the 3 in your speed is a typo.

Answer 2

it is
