the first question flips that on its head and asks me to find the W/V
This I'm afraid is one of those completely stupid questions that have no bearing on anything you will ever do once you've passed the exam, like the one in Air Law that asks you what colour paper the Diet of Worms was printed on. Or the one where you're expected to remember whether some visibility limit is 1500m or 1800m (real life answer: "who cares, if the vis is less than 5km I'm staying on the ground anyway").
Yes in theory you could fly a heading, and work out from the map (or, more likely, the GPS) what your actual track and groundspeed are, and then get out the whizz wheel and calculate the wind velocity, but nobody does that - why would anyone want to?? Anyway nobody uses the whizz wheel in flight, not even those who use it for flight planning on the ground.
Besides ... my whizz wheel comes with a little booklet with worked examples of each type of problem - you'd use the booklet in real life, wouldn't you, nobody ever told me not to use it in the exam.
