Question

A ship sends out ultrasound that returns from the seabef and is detected after 3.42 s. If the speed of ultrasound through seawater is 1531 m/s, what is the distance of the seabed from the ship ?​

Answer 1

Hey Pretty Stranger!

Given,

• Time between transmission and direction, t = 3.42 seconds.

• Speed of ultrasound in Sea water, v = 1531 m/s

• Distance travelled by the ultrasound = 2 × depth of the sea.

Where d is the depth of the sea.

$\sf \: 2d = speed \: of \: sound \: \times time$

$\sf \: 2d = 1531 \times 3.42$

$\sf \: 2d = 5236 \: m$

$\sf \: d = 2618 \: m$

$\therefore$ The distance of the seabed from the ship is 2618 m or 2.62 km
