Question 881974: A plane flies 600 miles with a tail wind in 2 hours. It takes the same plane 4 hours to fly the 600 miles when flying against the wind. What is the plane's speed in still air? I tried to make 2 formulas both equaling 600 but didn't know how to move on from there.

consider speed of plane as 'x' and speed of wind as'y'. In the direction of wind speed will be 'x+y' in opposite direction speed will be'x-y'.
x+y=(600/2)
x-y=(600/4)
from two equations speed of plane is 225miles/hour
