A2. A man standingstanding 150m beforea tower firesgun and heard the echo 0.9 second later. Calculate the speed of the sound​

The speed of the sound will be "16.67 m/s".The given values are:Distance,D = 150 mTime,T = 0.9 secondAs we know,→ [tex]Distance = Speed\times Time[/tex]or,→ [tex]Time = \frac{Distance}{Speed}[/tex]By substituting the values, we get→           [tex]= \frac{150}{0.9}[/tex]→           [tex]= 16.67 \ m/s[/tex]Thus the above is the appropriate answer.

Hello! For this excersice let's applicate the formula:[tex]\boxed{\boxed{d=vt}}[/tex]Data:d = Distance = 150 mv = Velocity = ¿?t = Time = 0,9 sNow, let's replace according the formula:[tex]\boxed{150 \ m = v * 0,9 \ s}[/tex]Clear v:[tex]\boxed{\dfrac{150 \ m}{0,9 \ s} = v}[/tex]Resolving:[tex]\boxed{166,67 \ m/s = v}[/tex]The velocity is 166,67 meters per second.
