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
