How do I work this problem? Flying with the wind, an airplane can travel 1080 miles in six hours, but against the wind, it goes 360 miles in half the time. Find the air speed and wind speed

Please label it so a teacher of that subject will read your post. I only opened it out of curiosity. Look to the left, upper-left hand side of the red menu for a School Subject that we can recognize.

plane's normal speed = s

wind speed = w

1080(s+w) = 6

360/(s-w) = 3

6s + 6w = 1080

3s - 3w = 360

12s = 1800

s = 150

w = 30
