Explanation:
It is given that,
Initial speed of both bicyclist and a runner is 0 as they both are waiting at a red light,
When the light turns green they start to speed up.
Final speed of the bicyclist is 20 mph in 5 seconds

What is Power?
Electric power is the rate at which an electric circuit transfers electrical energy per unit time.
Typically, electricity is generated by generators, but it can also be supplied by sources such as electric batteries. The electric power industry typically distributes it via an electric power grid to businesses and homes (as domestic mains electricity).
Transmission lines allow electric power to be delivered over long distances and used for high-efficiency applications such as motion, light, or heat. Electric charges are converted to other forms of energy when they pass through an electric potential difference (voltage).
