A salesman drove from his home to a nearby city at an average speed of 40 mi/. He returned home at an average speed of 50 mi/h. What was his average speed for the entire trip?

I tried this question, and apparently the answer isn't 45 mph. It's something of a trick question. Any help/hints would be much appreciated!
