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 400 kw / h ( kilowatts per hour ) . on a stormy day a windmill produces 20 % more energy . how much kw / h can 3 windmills produce in two hours on a stormy day ?
n0 = 20.0
n1 = 400.0
n2 = 20.0
n3 = 3.0
t0 = n0 * n1
t1 = t0 / 100.0
t2 = n1 + t1
t3 = n3 * t2
answer = t3 * 2.0
