You can put this solution on YOUR website! Your friend flew to Miami in a plane that averaged 600 mi/h. She drove back home, averaging 50 mi/h. What is her average speed in miles per hour for the whole trip? Assume the distances by plane and car are equal.
------------
avg speed = 2*600*50/(600+50)
=~ 92.3 mi/hr
