Hopefully this is in the right place...
Here is my problem, thanks in advance...!
"Let's say a jet leaves Los Angeles and flies straight across the country to New York City. Thanks to the jet stream, the jet enjoys a brisk tailwind and averages 600mph for the 3000 mile distance. On the return flight, back to L.A., the jet encounters the same jet stream, this time of course as a headwind. Therefore, the jet averages only 4000mph for the 3000 mile return trip.
What is the average speed of the plane for the entire round-trip flight or journey"?
