Settle a bet: Mach speeds

The above question should read, "...turn around and fly back to
airport "A" now with a 20 mph tailwind at the same TAS."

In other words, if you takeoff from airport "A" and fly 200 miles into
a 20 mph headwind to airport "B" at 100 mph (TAS) and then turn around
and fly back to airport "A" now with a 20 mph tailwind at the same TAS
will you complete the roundtrip flight in the same time as if you had
made the flight in no-wind conditions?

Okay, I'll bite.

Looks like the no-wind solution is 4 hours, the headwind/tailwind
solution is 4.17 hours.

Just in case I win, I prefer Lagavulin 16. I'll skip the seegar.

Al Gerharter was the first to answer correctly, but disqualified
himself by admitting that he's an old hand instructor so it looks
like you won indeed. Congratulations! A large bucket of Lagavulin
16 is on the way...

Because you spend more time going against the wind and fighting it, than you
spend with the wind and benefitting from it, so thats why you lose time

Amazing how many folks fail to grasp this concept.

Instead of forever battling headwinds, one of these days I'm going
to get in and burn an entire tank of gas or two while intentionally
flying WITH the wind and see where the tailwinds take me....
