Answer 1

To calculate the time it takes for the sound to travel 2 kilometers (2000 meters), we can use the formula:

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

Substituting in the values:

\[
\text{Time} = \frac{2000 \text{ m}}{340 \text{ m/s}} \approx 5.88 \text{ seconds}
\]

Rounding this, it is approximately 5.9 seconds.

So, the correct response is:

**5.9 seconds**
