Answer:
the distance between the person and the hill is 330 m.
Explanation:
Given;
speed of sound in air, v = 330m/s
time of sound travel, t = 2 s
The distance between the person and the hill is calculated as;
[tex]Distance = Speed \ \times \ Time\\\\Time \ of \ echo = \frac{2\ \times \ distance}{speed} \\\\distance = \frac{Time \ of \ echo \ \times \ speed}{2} \\\\distance = \frac{2 \ \times \ 330}{2} \\\\distance = 330 \ m[/tex]
Therefore, the distance between the person and the hill is 330 m.
