OK.
1 - TAS along your magnetic course is 75.6 knots. With 20 knots of headwind component, your ground speed is
55.6 knots.
2 - I think this question is sort of a trick question to see if you're paying attention. It says the true
course is 055. Course is what you wan to fly. The only difference between true course and magnetic course is the magnetic variation. So, add 6 degrees of west variation to your true course and you get a magnetic course of
061.
3 - This is just simple math. Point A distance from equator in degrees plus point B distance from equator in degrees (since they are on opposite sides of the equator). They already give you both numbers. Just add them together. 15 54'30" + 10 33'30" =
26 28' 00"
