A man flies a small airplane from Fargo to Bismarck, North Dakota  a distance of 180 miles. Because he is flying into a head wind, the trip takes him 2 hours. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1 hour 12 minutes. What is his speed in still air, and how fast is the wind blowing?

Best ResponseYou've already chosen the best response.0(nw)2=180 (n+w)1.2=180  2n2w=180 1.2n+1.2w=180  6n6w=540 6n+6w=900  12n=1440 n=123  substitute n into one of original equations 2(123)2w=180 w=33 did i do that right?
