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.
Divide the distance by the time. That is how you get velocity.
Given: t (time): 0.29s (2 sig figs)*
d (distance): 100m
v = d / t
v = 100m / 0.29s
v = 340 m/s (remember two sig figs)*

To determine the velocity of sound waves in the given scenario, we can use the formula:
Velocity = Distance / Time
In this case, the distance sound travels across the football field is 100 meters, and the time it takes is 0.29 seconds. Plugging these values into the formula, we get:
Velocity = 100 meters / 0.29 seconds
Calculating this, we find that the velocity of sound waves in the given scenario is approximately 344.83 meters per second.
