Question

A sound wave moving with a speed of 1500 m/s is sent from a submarine to the ocean floor. It reflects off the

ocean floor and is received 15s later. What is the distance between the submarine and the ocean floor?

Answer 1

the distance between the submarine and the ocean floor is 11,250 m

Step-by-step explanation:

Given;

speed of the wave, v = 1500 m/s

time of motion of the wave, t = 15 s

The time taken to receive the echo is calculated as;

`time \ of \ motion \ (t) = (total \ distance )/(speed \ of \ wave) = (2d)/(v) \\\\2d = vt\\\\d = (vt)/(2) \\\\d = (1500 * 15)/(2) \\\\d = 11,250 \ m`

Therefore, the distance between the submarine and the ocean floor is 11,250 m
