Frequency = (wave speed) / (wavelength)
Frequency = (24 m/s) / (2 m)
Frequency = 12 per second .

Answer:
Ari catches up to Amanda at 19.3 meters
Explanation:
We have given Ari is swimming a 25-meter race.
It is given that after swimming 6 meters she catches up to Amanda in a ratio of 7:3 from the 6-meter mark.
So ,The distance between 6 meters and 25 meters = 25-6 =19 meters
It is given that she catched Amanda in ratio 7:3
So, she catched her at of the distance
So, the distance at which she catched Amanda
Ari catches 13.3 metres from 6 m marks
So the total distance = 13.33+6 =19.33 meters
So Ari catches up to Amanda at a distance of 19.33 meters
The magnitude of displacement =
the distance between start-point and end-point,
regardless of the route followed along the way.
Any motion that ends up where it started has zero displacement.
An object on a circular path starts over at zero displacement every time
it completes a full revolution. So does a race-car on a track.
