A physically fit person can sustain an output of 95 watts of useful power for several hours, possibly by pedaling a mechanism connected to an electric generator. Ignoring issues related to generator efficiency and practical factors like resting periods, how many individuals would be required to power a 4.64-kilowatt electric clothes dryer?

To determine the number of individuals required to power a 4.64-kilowatt electric clothes dryer, you first need to convert the dryer's power requirement to watts, as power is usually measured in watts.

1 kilowatt (kW) = 1,000 watts (W)

So, for a 4.64 kW electric clothes dryer:

4.64 kW * 1,000 W/kW = 4,640 watts

Now, if one person can sustain a power output of 95 watts, you can calculate the number of people needed by dividing the total power requirement of the dryer by the power output per person.

Number of individuals required = Total power required / Power output per individual

Number of individuals required = 4,640 W / 95 W/person

Number of individuals required ≈ 48.84

Since you can't have a fraction of a person, you would need to round up to the nearest whole person.

Therefore, you would need 49 individuals to power a 4.64-kilowatt electric clothes dryer.
