An airplane started its flight from point A towards point B at the same time as a helicopter started its flight from point B towards point A. When they meet, a helicopter flew 100 miles less than an airplane. After the meeting point, a helicopter needs 3 hours to reach point A, and an airplane needs 1 hour and 20 minutes to reach point B. Find the average speed of a helicopter and the distance between points A and B.
