**bobpursley**, Friday, October 8, 2010 at 3:57pmMake an angle measured from S counterclockwise to heading (somewhere SE)

the Easterly component has to be 75km/hr

The resultant is S, and the heading is 450

Then TanTheta= 75/desired resultantvelocity

TanTheta= 75/(450/2)

solve for Theta.

Your airspeed should be

SinTheta= 75/desiredairspeed

solve for desired airspeed.
