Answer 1

Explanation:

Hey there !

Solution :

We know that,

Distance = Speed * Time

Given that, Speed of Sound in air is 340 m / s

Also time = 3.41 seconds 

But here the time includes both the initial falling time and also the traveling time of sound. Hence it becomes twice the distance traveled. Hence we must divide the final distance by 2 to get the correct depth of well. Hence on calculating final depth we get,

Final depth = D = speed * time

=> D = 340 m / s * 3.43 

=> Final depth ( Counting twice ) = 1159.4 m

So this is twice the distance travelled. Hence original distance is 

D = 1159.4 / 2 => 579.7 m

Hence the distance or depth of the well is 579.7 m

Hope my answer helped !!!!!❤️❤️

please mark me as brainliest!!!!!

Answer 2

Answer:

the speed of sound in air is 335m/s

distance travelled by sound=3.41*335

=1142.35m

as the sound return also so the distance become twice

depth =1/2 of distance travelled

depth=1/2*1142.35

=571.125
