X=speed of the first plane. (east)
2x=speed of the second plane (west).

we can suggest this equation:
3(x+2x)=2700
3(3x)=2700
9x=2700
x=2700/9
x=300

speed of the first plane=300 miles/h
speed of the second plane=2x=2(300 miles/h)=600 miles/h.

Answer: the speed of the first plane was 300 miles/h, and the speed of the  second plane was 600 miles/h.
