Question

An average car engine can produce about 100 horsepower. How many 100-watt light bulbs does it take to use the same amount of power?

Answer 1

745

Explanation:

1 horsepower is about 745.7W

So 100 hp = `74570"W"`

Since each bulb consumes `100"W"` of power the number of lightbulbs the engine could power `=74570/100=745.7`

Which rounds down to 745.
