Answer:
Ali hear the sound in 0.046 seconds.
Explanation:
Given:
Distance between Ali and Abdi = 300m
Speed of sound in steel = 6500m/s
To Find :
How much sooner does Ali hear the sound = ?
Solution:
We can find the time in which the sound made by Abdi with a stone on the rail by using the speed formula
We know that
[tex]Speed = \frac{Distance}{time}\\[/tex]
On substituting the given values,
[tex] 6500 = \frac{300}{time}\\[/tex]
[tex] time = \frac{300}{6500}\\[/tex]
[tex] time = \frac{300}{6500}\\[/tex]
Time = 0.046 seconds
