Avila · Answer 1

The bottom of the ocean is 6 km

Explanation:

Given data,

The time taken by the SONAR to reach the bottom of the ocean and return is, t = 8 s

The speed of the sound in water, v = 1500 m/s

The formula for distance traveled by the SONAR is,

d = v x t

Substituting the values

d = 1500 x 8

= 12,000 m

The half the distance the SONAR covered is equal to the depth of the ocean

s = d/2

= 12000/2

= 6000 m

Hence, the bottom of the ocean is 6 km
