Sunday evening trivia question
Currently revising for my navigation question but keep getting this question wrong and I have no idea how the correct answer is actually correct.
Given Hdg of 138T, a track of 141T, a TAS of 122kts and a G/S of 101kt, what is the W/V?
a) 136/26
b) 120/21
c) 141/19
d) 131/21
I come up with ~125/22 (which isn't one of the options!) but the actual answer is D (131/21). All of the other W/V questions I've attempted I've managed to get right but it's just this little fella that has me stumped. I'm about to chuck either the computer or CRP (or both) out of the window.
Can someone explain how to get the right answer?
Thanks
