a small plane flying into the wind takes 3 hrs 20 min to complete a flight of 960 km. Flying with the wind the same plane takes 2 h 30 min to make the trip.what is the speed of the plane? what is the speed of the wind?

w=speed of wind
a=speed of airplane
Use speed*time = distance
(aw)*(10/3)=960 ...(1)
(a+2)*(5/2)=960 ...(2)
Solve for a and w.
