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,
→
or,
→
By substituting the values, we get
→
→
Thus the above is the appropriate answer.

Hello! For this excersice let's applicate the formula:
Data:
d = Distance = 150 m
v = Velocity = ¿?
t = Time = 0,9 s
Now, let's replace according the formula:
Clear v:
Resolving:The velocity is 166,67 meters per second.
