Question

Assuming that the average speed of sound waves in water
is 1,500 meters per second, determine, in seconds, how
long it takes a sonar signal to hit the bottom and return to
the recorder if the water depth is 7,500 meters.

Answer 1

The time it takes for the sound to reach the depth of the water is 5 seconds.

Data;

• Velocity/speed of sound = 1500m/s
• distance of water = 7500m
• Time?

Speed/ Velocity

To solve this problem, we can simply use the formula of speed or velocity which is the ratio between distance and time.

Let's substitute the values and solve

$velocity = \frac{distance}{time} \\time = \frac{distance}{velocity} \\time = \frac{7500}{1500} \\time = 5s$

The time it takes for the sound to reach the depth of the water is 5 seconds.
