1489.5

Answer 2

The distance from train is 1489.5 meters.

Explanation:

Given:

if you see the steam from its nozzle 4.5 seconds before you hear its sound.

Speed of sound as 331 m/sec.

To Find:

The distance form train.

Formula Used:

$Speed=\frac{Distance}{Time}$    ------------- formula no.01.

Solution:

As given- if you see the steam from its nozzle 4.5 seconds before you hear its sound.

It means,  Time=4.5 seconds

As given- speed of sound as 331 m/sec.

Speed of sound =331 m/sec.

Applying the formula no.01.

$Speed=\frac{Distance}{Time}$

$331=\frac{Distance}{4.5}$      

$Distance=331\times 4.5$

               $= 1489.5 \ meters$      

Thus,the distance from train is 1489.5 meters.
