Answer:
- <u>1,000 m (rounded to one significant figure)</u>
Explanation:
The equation is:
- speed = <em>340m/s</em>
- time = <em>6 seconds</em> (the <em>sound</em> travels the distance back and forth)
Hence, the <em>distance</em> between the<em> ship </em>and the <em>cliff</em> is half the distance traveled by the sound:
- 2,040m / 2 = 1,020 m.
If you round to one significant figure, because the time has just one significant figure, the answer is 1,000m.
