Hi guys

I'm having trouble with this question from the text book

The power P produced by a wind turbine is proportional to the cube of the wind speed S. A wind speed of 44km per hour produces a power output of 750 kilowatts. find the out for a wind speed of 65 km per hour.

hi so to solve this do i just devide 750 by 44 which gives 17.045 and then do i do something with that like multiply it by 65.

Please help
