Answer:
The bottom of the ocean is 6 km
Step-by-step 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
