If a plane travels 600 miles to a certain point against the wind and takes 3 hrs, and goes back the same distance but with the wind and it takes 2 hrs, what is the speed of the airplane?

My best guess is the plane is travelling at 300 miles per hour to get to its destination in 2 hours. If it takes 3 hours to get 600 miles, then divide 3 into the 600 and it would be doing 200 miles per hour. Same thing with coming back, it is still 600 miles, but only takes 2 hours so divide the 2 into the 600, comes out 300 miles per hour. I think the wind thing was put there to confuse you.

speed = distance/time
600 miles/3 hours = 200 mi/hr or mph
600 miles/2 hours = 300 mi/hr or mph
average speed = (initial Speed + finish Speed)/2
200 + 300 = 250 mi/hr or mph

200 mph going there and 300 mph going back
