Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

As wind turbine is rotating, but wind speed is in specific direction. So at different points, the relative speeds will be different. At point when turbine is moving in same direction as wind, its speed will be = । true wind speed - turbine speed। =। 30*pie - 10। The point where they both are in opposite direction, its speed will be = । true wind speed + turbine speed। =। 30*pie + 10।
