A windmill is taking advantage of strong air currents in order to produce electrical energy. On a typical day the wind speed is around 20 mph and in that speed the windmill produces 800 kw/h (kilowatts per hour). On a stormy day a windmill produces 20% more energy. How much kw/h can three windmills produce in two hours on a stormy day?  Choose the correct choice: A) 2880. B) 4860. C) 5780. D) 5760. E) 6380.
1 windmill:   Normal 5760.ay = 800 kw/h   Stormy 5760.ay = 800*1.2=
