the 4200 km trip from new york to sanfransico takes 7 h flying against the wind but only 6h returning find the speed of the plane in stil air and the wind speed.
---------
Use d = r*t
--> r = d/t to find the 2 groundspeeds
The plane's airspeed is the average of the 2 groundspeeds.
The windspeed is the difference between airspeed and groundspeed.
