Question

The speed of sound in water is 1498 m/s. A sonar signal is sent straight down from a ship at a point just below the water surface, and 1.75 s later, the reflected signal is detected. How deep is the water

Answer 1

Answer:

The water is 1310.75 meters deep.

Explanation:

The question gives us the speed of sound and the time the sonar signal takes to travel to the bottom of the water and back.

To find out the distance, we should first divide the time in half, so we only consider the time taken for the sound to reach the bottom of the water body.

This means:

Time = 1.75 / 2 = 0.875 seconds

The distance traveled in this time is:

Distance = Speed * Time

Distance = 1498 * 0.875

Distance = 1310.75 meters    

Thus, the water is 1310.75 meters deep.
