Question:

If a 4.5-meter wave traveled at a speed of 15 m/s, what would its frequency be?

A 3.33 Hz
Explaination

In order to find the frequency, you will need to use the equation for speed: speed equals wavelength times frequency. Thus, 15 = 4.5 times\u00A0Frequency or 15 \u00F7\u00A04.5 = 3.33 Hz.
