**Reiny**, Tuesday, September 25, 2012 at 11:08pmspeed of wind --- x mph

speed of plane --- 300 mph

speed against wind --- 300-x

speed with the wind --- 300+x

time for Atlanta to Dubuque = 900/(x+300)

coming back when time was the same --- 750/(300-x)

900/(300+x) = 750/(300-x)

270000 - 900x = 225000 + 750x

45000 = 1650x

x=300/11

x = 27.2727... mph
