Plane  going East	x	mph						
Plane going West	x+	75	mph					
..								
They are moving away from each other								
								
So add up their speed.								
								
combined speed = x+x	+	75			
(	2	x	+	75	)			
Time =	3	hours						
Distance =   	3075	miles						
Distance = speed * time	
							
(2x+75)*3=3075

6.00	x	+	225	=	3075			
6	x	=	3075	+	-225			
6	x	=	2850					
/	6							
x=	475	mph						
Plane  going East	=	475	mph					
Plane going West	475	+	75	=	550	mph
