Answer:
The speed of sound is affected by temperature and humidity. Because it is less dense, sound passes through hot air faster than it passes through cold air. ... The attenuation of sound in air is affected by the relative humidity. Dry air absorbs far more acoustical energy than does moist air.
The average speed is 10 m/s.
Explanation:
The motion of the object is divided into two parts.
In the first part, the object covers a distance of
In a time interval of
In the second part, the object is a t rest, so it covers a distance of
In a time interval of
The average speed for the trip is given by the ratio between the total distance and the total time taken, therefore:
