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
Is the answer 85m?
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.
since distance = speed * time, you have
2d = (340 m/s)(0.5 s)
Now just find d.
To determine the child's distance from the wall, we can use the equation:
Distance = (Velocity of sound × Time) ÷ 2
Given:
Velocity of sound = 340 meters per second
Time = 0.5 seconds
Plugging in the values into the equation, we get:
Distance = (340 × 0.5) ÷ 2
= (170) ÷ 2
= 85 meters
Therefore, the child is standing 85 meters away from the wall.
