Answer 1

To find the time it takes for sound to travel 2 kilometers, we can use the formula:

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

Here, the distance is 2 kilometers (which is 2000 meters) and the speed of sound is 340 m/s.

Now, plug 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**.
