Incomplete Question!
If it is a question from physics class 8th book. Page No.168 . Chapter= Sound
Then, the question will be this!
A man is cutting down a tree with an axe, he hears the echo of the impact of the axe hitting the tree after 1.6 sec. The speed of sound is 330 m/s. How far is the tree from the obstacle?
So, the answer is:
given
Time(t)= 1.6 sec
Speed(v)=330 m/s
Distance(d) = ?
We know,
t = 2d/v
∴d = vt/2
=330 x 1.6/2
=264 m
Hence distance = 264 m
