I am looking for formula and easy explanation for calculating the wavelength of a sine wave. So far I have not been able to calculate the example I want to do as I could not understand the resources I've found from Google.
What is the wavelength of sine wave? Given frequency, distance and time.
For instance, a 0.42 MHz sine wave takes 3.3 µs to travel 2500 meters.
I am asking for patience I know this might look amateur for some but I am learning basics and I struggle to find the answer.

$$speed = \frac{distance}{time \; to \; traverse \; it} $$
$$= \frac{2500}{3.3 \times 10^{-6}} \cdot \frac{[m]}{[s]} = 7.58 \times 10^8 m/s$$
That's physically impossible - it's faster than the speed of light (\$3 \times 10^8 m/s\$). Check again what the speed of the signal should be.
anyway, once you find it:
$$wavelength = \frac{speed}{frequency}$$
