I remember one of the Manhattan GMAT instructors (I believe it was Horacio Quiroga) describing a trick for round trip (or half the distance) weighted average rate problems. I can't find this anywhere though. Can someone help me?

Thanks,
Patrick

Hi Patrick,
I'm not sure what Horacio's trick is, but let me email him and I will post his response here.
