Answer 1

Hey mate !!

Here's your answer !!

We know the formula:

Distance = Speed * Time.

Given that:

1. Distance = 1650 m

2. Speed = 330 m / s

To find :

1. Speed = ?

Proof :

Substituting the values in the formula we get,

= 1650 m = 330 m / s * Time

=> Time = 1650 m / 330 m / s

=> Time = 5 seconds

Hence it will take 5 seconds for B to hear the sound of A firing the gun.

Hope my answer helped !!

Cheers !!
