Expert Solution
Introduction:
We know that power is rate of energy consumption or conversion.
We know the total power needed to light the ball's LEDs. We also know the power provided by each bike. Hence we can find the number of bikes required to light up ball's LEDs. We are given the time required for the LEDs lighting and number of bikes provided to us. We can find the time required for pedaling to generate this amount of energy for LEDs lighting.
