Answer:
The distance between the submarine is, d = 9933.3 m
Explanation:
Given data,
The speed of the submarine A and B, v = 5 m/s
Submarine A produces a pulse of sound to detect B at a distance, d = 10 km
= 10000 m
The speed of sound in water is, V = 1500 m/s
The time period to receive echo is given by the formula,
t = d / v
= 10000 / 1500
= 6.67 s
The distance between the submarine is given by the relation
d = 10000 - 2(v x t)
= 10000 - 2(5 x 6.67)
= 9933.3 m
Hence, the distance between the submarine is, d = 9933.3 m
