Options

A. 1300 metre
B. 2000 metre
C. 3650 metre
D. 3300 metre

Answer

To solve the problem, we need to find the distance that sound travels in 10 seconds. We know that sound travels at a speed of 330 meters per second.

Here’s a step-by-step solution:

### Step 1: Identify the given values
- Speed of sound = 330 meters/second
- Time = 10 seconds

### Step 2: Use the formula for distance
The formula to calculate distance is:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]

### Step 3: Substitute the values into the formula
Now, we can substitute the given values into the formula:
\[ \text{Distance} = 330 \, \text{meters/second} \times 10 \, \text{seconds} \]

### Step 4: Perform the multiplication
Now, we calculate the distance:
\[ \text{Distance} = 330 \times 10 = 3300 \, \text{meters} \]

### Step 5: State the final answer
The distance of the thundercloud from the observer is 3300 meters.
