Please help me on this:
Wind farms are a source of renewable energy found around the world. The power p (in kilowatts) generated by a wind turbine varies directly as the cube of the wind speed v (in meters per sec.). If a turbine generates 700kWin a 5 m/s wind, how much power does it generate in a 16m/s wind?
A. 20480kW, B. 22938kW, C. 11469kW, D. 7168kW

@Hero can you please help me?

Actually, 

Use this formula for direct variation

$p = kv^3$

Ok will you please help me on which numbers go into which variables so I can see it set up and solve it?

Never mind I got B by solving for K then plugging the K into the original formula and placing 16 in for v :)
