In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. In water waves, energy is transferred through the vibration of the water particles.
The average speed is mph (mile per hour)
200m/5h = 40m/h (simlified)
divide by 5 on both sides (since you are trying to get per hour)
40mph is your answer

Answer:
Length= 20
Width= 4
Step-by-step explanation:
First, you can turn this into an equation:
Length= L
width= w
So L=5w
And using the area formula for rectangles, we get L*w=80.
Now, to solve, we only need to substitute 5w into L.
Now we have 5w^2=80. We divide by 5 on both sides to get w^2=16.
We take the square root of both sides. since the length and width of an rectangle cannot be negative, we are left with only w=4.
So plugging back in, we get L=20.
To check, 20*4=80.
