miles against the wind. Find the speed of the wind.
***
let c=speed of wind
200+c=speed of plane with the wind
200-c=speed of plane against the wind
travel time=distance/speed (same for both directions)
..
500%2F%28200%2Bc%29=300%2F%28200-c%29
500(200-c)=300(200+c)
100000-500c=60000+300c
800c=40000
c=50
speed of wind=50 mph
