Answer 2

Hiiii ❤️

Here's the answer--->

Given -->

•Time taken to hear echo (t ) = 3s

•Speed of sound (v ) = 330m/s

•Distance = ?

** To find Distance,

Formula used = >

• Distance ( d ) = (v × t ) / 2

Putting the values in given equation ,

Distance (d ) = ( 330 m/s × 3s ) / 2

= > 990 m / 2 = > 495m.

Hence, final answer is 495m ..
