The thunder of a lightening in the sky is heard 10 seconds after the flash of light. If the speed of sound is 330 m/s, the distance of lightening is

Options

A. 3.3 m
B. 33 m
C. 330 m
D. 3300 m

Explanation

To find the distance of lightning based on the time it takes for the thunder to be heard after the flash of light, we can use the formula for distance:

**Step 1: Identify the given values.**
- Speed of sound (v) = 330 m/s
- Time (t) = 10 seconds

**Step 2: Use the formula for distance.**
The formula for distance (d) is given by:
\[ d = v \times t \]

**Step 3: Substitute the values into the formula.**
Now, substitute the known values into the formula:
\[ d = 330 \, \text{m/s} \times 10 \, \text{s} \]

**Step 4: Calculate the distance.**
Now, perform the multiplication:
\[ d = 3300 \, \text{m} \]

**Step 5: Convert the distance to kilometers (if necessary).**
To convert meters to kilometers:
\[ 3300 \, \text{m} = 3.3 \, \text{km} \]

**Final Answer:**
The distance of the lightning is 3300 meters or 3.3 kilometers.
