Respuesta :

Answer:

The wall is 680 meter away from the person.

Explanation:

Given data

Speed of sound = 340 [tex]\frac{m}{s}[/tex]

Given that Persons said hello toward the opposite side she has an echo hello 4 seconds later means it takes 2 seconds for the sound to reach the wall & again 2 seconds to reach the persons ear.

Therefore the distance between the person & wall is

D = speed × Time

D = 340 × 2

D = 680 meter

Therefore the wall is 680 meter away from the person.
