Answer:
1,000 m (rounded to one significant figure)Explanation:
The equation is:
[tex]distance\text{ }traveled\text{ }by\text{ }the\text{ }sound=speed\times time[/tex]
speed = 340m/stime = 6 seconds (the sound travels the distance back and forth)[tex]distance\text{ }traveled\text{ }by\text{ }the\text{ }sound=340m/s\times 6s=2,040m[/tex]
Hence, the distance between the ship and the cliff 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.
