Velocity is defined as the rate of change of displacement with respect to time. It is a vector quantity because it requires both magnitude and direction. It is expressed in meters/second (m/s).

Mathematically,

[tex]\text{Velocity}=\frac{d}{t}[/tex]

Where,

d = displacement = 100 meters

t = time taken = 0.29 seconds

Putting the values in above equation, we get:

[tex]\text{Velocity}=\frac{100m}{0.29s}\\\\\text{Velocity}=344.82m/s\approx 345m/s[/tex]

The sound wave is moving with a velocity os 345 m/s in the direction of the field.

Hence, the correct answer is Option C.

At 25°C, sound can travel 100 meters across a football field in 0.29 seconds. Determine the velocity of these sound waves in the direction they travel across the field. A) 0.0029 m s B) 29 m s C) 345 m s D) 34,500 m s
