Question 809232: A plane travels 1200 mi with the wind in 2 hours. The return trip against the wind takes 3 hours. Find the rate of speed of the plane in still air.
*Only trying to find rate of speed of plane in still air, not wind speed*
Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! s = d / t
s + w = 1200 / 2 = 600
s - w = 1200 / 3 = 400
---
s = 600 - w
s = 400 + w
600 - w = 400 + w
200 = 2w
w = 100
Answer:
s = 500
