Speed = distance / time.
Speed of him leaving the nest:
S = 100 / 20sec
5 m/s.
Catching the snake:
S2 = 50 / 5sec
10 m/s.
Average of 5& 10 = 7.5
7.5 m/s has to be the answer.
Explanation:
velocity: average velocity equals Displacement /change in time.
Kinetic energy: K=1/2mv^2 (m = Mass) ( v = Velocity).
speed using the kinetic energy is also KE =1/2mv^2
(M in Kg) (V in m/s)
The total amount of energy per hour is 
Explanation:
In this problem we are told that the amount of energy reaching a square meter in the United States per hour is

The total surface area of the United States is

And converting into squared metres,

Therefore, the total energy reaching the entire United States per hour is given by:
