Question

1. A boy fires a gun and another boy at a distance
of 1020 m hears the sound of firing the gun 3 s
after seeing its smoke. Find the speed of sound.​

Answer 1

Answer:

340m/ s.(d=Vt)

It is the answer

Answer 2

Answer:

340 m/s

Explanation:

Given,

Distance(d) = 1020m

time(t) = 3s

To Find :-

Speed(s)

Formula  Required :-

$speed=\dfrac{distance}{time}$

→ s = d/t

Solution :-

$s=\dfrac{1020m}{3s}$

$=\dfrac{1020}{3}m/s$

= 340m/s

Speed(s) = 340m/s

Know More :-

1) s = ut + 1/2 at²

2) s = vt - 1/2at²

3) s = (u+v)t/2

• s = distance
• u = initial velocity
• v = final velocity
• a = acceleration
• t = time
