Question

A SONAR transmits an ultrasonic signal towards the bottom of the sea. The time taken by the sound to reach back to the receiver was 2.4sec .If speed of ultrasonic sound is 1560m/s , find the depth of sea.


pls answer with a little explanation​

Answer 1

Time taken to reach back (t)= 2.4 s

Speed of sound (s) = 1560 m/s

Speed = Distance/Time

1560 = Distance/2.4

Distance = 1560×2.4

Distance = 3744 m

This was the distance of 2 way, then the original distance of one way = 3744/2

Distance = 1872 m

Answer 2

Answer:

Step-by-step explanation:

since distance = speed x time

and since sound travels to the depth of the sea and comes back

so the formula is 2d = v x t

2d= 1560 x 2.4

3744=2d

d=3744/2

= 1872m
