Sound produced at a point is heard by a person after 5 second, while the same sound is heard by another person after 6 seconds. If the speed of sound is 300 m/s, what could be the maximum and minimum distances between the two persons? A. 1.8 km, 0.15 km B. 2.2 km, 0.20 km C. 2.8 km, 0.25 km D. 3.3 km, 0.30 km

The maximum distance between the two persons is 300 m/s * 6 s = 1800 m = 1.8 km.
The minimum distance between the two persons is 300 m/s * 5 s = 1500 m = 1.5 km.
Therefore, the correct answer is A.

Option B is incorrect because the maximum distance cannot be less than 1.8 km.
Option C is incorrect because the minimum distance cannot be greater than 1.8 km.
Option D is incorrect because the maximum distance cannot be less than 1.8 km and the minimum distance cannot be greater than 1.8 km.
