A gun is fired at a distance of 3.32 km from Chauhan. He hears its sound 10 seconds later. Find the speed of the sound.

Options

A. 301 m/s
B. 302 m/s
C. 332 m/s
D. 340 m/s

Answer

To find the speed of sound based on the information provided, we will follow these steps:

### Step 1: Understand the given information
We know that a gun is fired at a distance of 3.32 km from Chauhan, and he hears the sound 10 seconds later.

### Step 2: Convert the distance from kilometers to meters
Since speed is typically measured in meters per second (m/s), we need to convert the distance from kilometers to meters.
- Distance in kilometers = 3.32 km
- To convert kilometers to meters, we multiply by 1000 (since 1 km = 1000 m):

\[ \text{Distance in meters} = 3.32 \, \text{km} \times 1000 = 3320 \, \text{m} \]

### Step 3: Use the formula for speed
The formula for speed is given by:

\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

### Step 4: Substitute the values into the formula
We have the distance as 3320 meters and the time as 10 seconds. Now we can substitute these values into the formula:

\[ \text{Speed} = \frac{3320 \, \text{m}}{10 \, \text{s}} = 332 \, \text{m/s} \]

### Step 5: Conclusion
The speed of sound is therefore 332 meters per second.

### Final Answer:
The speed of sound is **332 m/s**.
