What is his speed and the wind speed

Question

A man flies a small airplane from cargo 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 and 12 minutes . What is his speed in still air, and how fast is the wind blowing .?

Answer 1

180 = 2(p - w)

180 = 1.2(p + w)

Can you solve for p or w and answer?
