Now, seriously !

There's a stream of objects flowing past you.

Ten of them pass you every second.

Each one is 2m long.

Don't you think you can figure out how fast they're flowing ?

Answer:

Below

Step-by-step explanation:

To find the wave speed of a wave you can use this formula :

wavespeed (v) = (frequency) x (wavelength λ)

Plug in our values :

v = (10Hz) x (2m)

v = 20 m/s

Hope this helps!
