An airplane averages 140 mph. If a trip from Atlanta to Charleston takes 2 hours going against the wind, and 1 hour 30 minutes on the return flight going with the wind, find the speed of the wind Solution Distance = Speed * Time (140 - w) * 2 = (140 + w) * 3 / 2 4(140-w) = 3(140 + w) 4*140 - 4w = 3*140 + 3w 140 = 4w + 3w 140 = 7w w = 20 mph .

- An airplane averages 140 mph. If a trip from Atlanta to Charleston takes 2 hours going against the wind, and 1 hour 30 minutes on the return flight going with the wind, find the speed of the wind Solution Distance = Speed * Time (140 - w) * 2 = (140 + w) * 3 / 2 4(140-w) = 3(140 + w) 4*140 - 4w = 3*140 + 3w 140 = 4w + 3w 140 = 7w w = 20 mph
