Answer:
0.1 seconds
Explanation:
An echo is the repetition of sound that results as a reflection from a surface. An echo of the sound produced can be heard only if it reaches our ear after 1 / 10th of a second. This is due to the persistence of sound. so that is why the echo reaches our ear after 1 / 10th = 0.1 seconds
