Two planes left an airport at noon. one flew east and the other flew west at twice the speed. after 3 hours the planes were 2700 mi apart. how fast was each plane flying

Let the speed of the  plane which flew east is x miles per hour .

And the speed of the plane fles west is twice of the speed of the plane flew east. THerefore speed of plane flew west is 2x miles per hour .

According to question

Dividing both sides by 9

Therefore speed of the plane flew east is 300miles/hour and speed of the plane flew west is 600miles/hour .
