Question

an observer A fires a gun and another observer B at a distance 1650 m away from A hears its sound . If the speed of sound is 330 m/s^-1 , find the time when B will hear the sound after firing by A.​

Answer 1

Answer:

5 seconds

Explanation:

Data provided in the question as per the question is as follows

Distance = 1,650 meter

Speed of the sound is 330 m/s

Based on the given information, the time taken is

As we know that

$Speed = \frac{Total\ distance}{Total\ time}$

So,

$Time\ taken = \frac{Total\ distance}{Speed}$

$= \frac{1,650}{330}$

= 5 seconds

We simply divided the total distance from the speed so that the time taken could be come and the same is to be considered
