Question

Hey Tori's are the rim of a canyon yells hello toward the opposite side she has an echo hello four seconds later if the speed of sound is 340 m/s how far away was the canyon wall that produced the echo?

Answer 1

The wall is 680 meter away from the person.

Step-by-step explanation:

Given data

Speed of sound = 340
`(m)/(s)`

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.
