Answer by ptaylor(2198) (Show Source): You can put this solution on YOUR website!
Distance(d) equals Rate(r) times Time(t) or d=rt; r=d/t and t=d/r
Let r=rate (speed) of plane in still air
And let w=speed of the wind
r-w=445 against wind, subtract wind speed.-----eq1
r+w=515 with wind, add wind speed----eq2
add eq1 and eq2 and we get:
2r=960
r=480----speed of plane in still air

Hope this helps--ptaylor
