Question

A ship sends a signal to the bottom of the sea it is received back after 4 secobds.if the speed of sound in water is 1500m/s,then what is the deptg ig the sea?

Answer 1

Let the depth of the sea be x meters.

During the entire journey, the sound travels twice the depth of the sea. Hence, the distance traveled by the sound = 2x

Speed of sound in water = 1500 m/s

Time taken by the sound during entire journey = 4 seconds

2x = speed × time

$\( x = \frac{1500 \times 4}{2}$

x = 3000 m

Hence, the depth of the sea is 3000 m.
