The average airspeed of a singleengine aircraft is 150 milesper hour. If the aircraft flew the same distance in two hours with the wind as it flew in 3 hours against the wind, what was the effect of the wind on the plane? What are the equations? What is wind speed?

I have now done several of this type for you, and you have not shown any sign of acknowledgement or effort on your part.
Give it a try and let me know how you did.
