Explanation:
120+ 120 = 240 miles divided 1 hours 20 seconds
Answer:Broadly speaking, all energy in the universe can be categorized as either potential energy or kinetic energy. Potential energy is the energy associated with position, like a ball held up in the air. When you let go of that ball and let it fall, the potential energy converts into kinetic energy, or the energy associated with motion.
EXAMPLES: There are five types of kinetic energy: radiant, thermal, sound, electrical and mechanical. Let's explore several kinetic energy examples to better illustrate these various forms.
When a reaction has reached equilibrium, the rate of the forward reaction<span> equals the rate of the reverse </span>reaction<span>, such that the concentrations of reactants and products remain fairly stable, in a chemical </span>reaction<span>. Hope this answers the question. Have a nice day.</span>

Answer:
Explanation:
A track 100m
The sprinter passes 12m mark in 1.8seconds
Let this be the initial point
d1 = 12m
t1 = 1.8seconds
And Passes the 56m mark in 6.7 seconds
Then, the second point is
d2 = 56m
t2 = 6.7 seconds
The sprinter velocity between this two position
Velocity is the rate of change of displacement
V = displacement / time taken
V = ∆x / ∆t
V = (x2 - x1) / (t2 - t1)
V = (56 - 12) / (6.7 - 1.8)
V = 44 / 4.9
V = 8.98 m/s
Then, the sprinter velocity between this two position is 8.98 m/s
