To determine which wave has a faster speed, we can use the formula for wave speed:

\[ \text{Speed} = \text{Wavelength} \times \text{Frequency} \]

Now we can calculate the speed of each wave.

For Wave W:

  • Wavelength = 5 meters
  • Frequency = 200 hertz

\[ \text{Speed of W} = 5 , \text{meters} \times 200 , \text{hertz} = 1000 , \text{meters/second} \]

For Wave X:

  • Wavelength = 3 meters
  • Frequency = 300 hertz

\[ \text{Speed of X} = 3 , \text{meters} \times 300 , \text{hertz} = 900 , \text{meters/second} \]

Now we compare the speeds:

  • Speed of Wave W: 1000 meters/second
  • Speed of Wave X: 900 meters/second

Based on this calculation, the conclusion that can be made is:

Wave W has a faster speed.
