To calculate the time it takes for the sound to travel 2 kilometers (2000 meters) at a speed of 340 m/s, you can use the formula:
\[
\text{Time} = \frac{\text{Distance}}{\text{Speed}}
\]
Plugging in the values:
\[
\text{Time} = \frac{2000 \text{ m}}{340 \text{ m/s}} \approx 5.88 \text{ seconds}
\]
Rounding this to one decimal place gives approximately 5.9 seconds.
So, the correct response is:
**5.9 seconds**
\[
\text{Time} = \frac{\text{Distance}}{\text{Speed}}
\]
Plugging in the values:
\[
\text{Time} = \frac{2000 \text{ m}}{340 \text{ m/s}} \approx 5.88 \text{ seconds}
\]
Rounding this to one decimal place gives approximately 5.9 seconds.
So, the correct response is:
**5.9 seconds**
