A small plane takes off and heads directly upwind to an airport 40 miles away. It takes 30 minutes to get there. The return trip takes 20 minutes. What is the speed of the wind in miles per hour?

40 miles/1/2 hr  = 80 m/hr

 

40 miles/1/3 hr = 120 m/hr              airplane speed = 100    wind = 20 m/hr
