If it takes a Sonar echo 8 seconds to reach the bottom of the ocean and return and we know that the speed of sound is 1500 meters per second, how far away is the bottom of the ocean?:


A) 4000 meters

B) 8000 meters

C) 6000 meters

D) 1200 meters

Respuesta :

Answer:

C) 6000 meters.

Explanation:

Hello.

In this case, since the speed is computed as the distance divided by the time to attain such displacement:

[tex]s=\frac{d}{t}[/tex]

Knowing that the speed is 1500 m/s and the required time is 4 s because is the half of the described travel, the distance is then:

[tex]d=s*t\\\\d=1500m/s*4s\\\\d=6000m[/tex]

Therefore, the answer is C) 6000 meters.

Best regards.
