speeding; the real thing!

Posted by Denis Borris on 30/6/2009, 3:57 pm, in reply to "Re: speeding along..."

OK; now that I've kinda tested (thanks Mark!):

A travelled from P to Q at a mph, returned at u mph; average speed = c

B travelled from P to Q at b mph, returned at v mph; average speed = w

C travelled from P to Q at c mph, returned at w mph; average speed = x

Gimme x in terms of a,b,u,v

For the Quixotic adventurer:
gimme an integer solution with x = 132
