A sonar device on a submarine sends out a signal and receives an echo `5 s` later. Calculate the speed of sound in water if the distance of the object from the submarine is `3625 m`,

Explanation

To solve the problem step by step, we will follow these instructions:

### Step 1: Understand the Problem
We are given the time taken for the echo to return (5 seconds) and the distance to the object (3625 meters). We need to calculate the speed of sound in water.

### Step 2: Identify the Total Distance Traveled
The sound wave travels to the object and then back to the submarine. Therefore, the total distance traveled by the sound wave is:
\[ \text{Total Distance} = 2 \times \text{Distance to Object} \]
