Answer: 8 meters per second

Step-by-step explanation:

Hi, to answer this, first, we have to divide the time counted by the number of waves, to obtain the time of each wave:

10 / 20 = 0.5 seconds per wave

Now, we simply divide the distance given by the time, to obtain the speed rate:

4/0.5 = 8 meters per second
