I'm really bad at direct and inverse proportion so i'm stuck on this question. "A wind turbine generates a power of p kilowatts when the wind speeds in w m/s. P is proportional to W cubed P=300 when W= 12 Find a formula for P in terms of W" How do i work this out?

P is directly proportional to W^3, so in other terms p=kw where k is a constant. Sub in the values given and find k, this gives a general form
