Child standing in front of a wall claps his hands and hears the Eco after 0.5 sec . Determine his distance from wall velocity of sound 340 meter per sec

Answer 1

since distance = speed * time, you have

2d = (340 m/s)(0.5 s)
Now just find d.

Answer 2

Is the answer 85m?

Answer 3

Answer 85m.
Adwita's answer is correct as per I have solved it.
2d=Speed(v)×Time
D=340×0.5/2
Therefore, D=85m.
