Question 1027316
Plane  	speed	x	mph					
wind   	speed	25	mph					
..								
against	wind   	x	-	25	mph			
with	wind   	x   	+	25	mph			
								
Distance against	wind   	572						
Distance with	wind   	682						
Time = same	equate the time against with time with current							
t=d/r								
572	/(x-	25	)=	682	/(x+	25	)	
572	*(x+	25	)=	682	*(x-	25	)	
572	x  	+	14300	=	682	x	-17050	
572	x  	-682	x   	=	-17050	+	-14300	
-110	x  	=	-31350					
/	-110							
	x=	285	mph
