You can put this solution on YOUR website! If one horsepower = .746 kilowatts, calculate the number of horsepower 1.2 x 10^9 watts
...
Use dimensional analysis to solve:
Horsepower=HP
kilowatts=kw
..
(HP/.746 kw)(kw/1000 watts)(1.2)(10^9)watts
kw and watts cancel out
HP=1.2(10^9)/.746(1000)
HP=(1.2/.746)10^6
HP=1.6086*10^6
