2. A man standing
standing 150m before
a tower fires
gun and heard the echo 0.9 second later. Calculate the speed of the sound​

Answer 1

Hello! For this excersice let's applicate the formula:

$\boxed{\boxed{d=vt}}$

Data:

d = Distance = 150 m

v = Velocity = ¿?

t = Time = 0,9 s

Now, let's replace according the formula:

$\boxed{150 \ m = v * 0,9 \ s}$

• Clear v:

$\boxed{\dfrac{150 \ m}{0,9 \ s} = v}$

• Resolving:

$\boxed{166,67 \ m/s = v}$

The velocity is 166,67 meters per second.

Answer 2

The speed of the sound will be "16.67 m/s".

The given values are:

Distance,

• D = 150 m

Time,

• T = 0.9 second

As we know,

→ $Distance = Speed\times Time$

or,

→ $Time = \frac{Distance}{Speed}$

By substituting the values, we get

→           $= \frac{150}{0.9}$

→           $= 16.67 \ m/s$

Thus the above is the appropriate answer.
