Hi
1) The problem should be solved by drawing a sketch
once u draw it u can calculate the length of the trk by using the pythagoras theorem
i.e. X^2= 40^2+40^2
X=56.56
We now the dist now. the time is given in the ques i.e. 15 mins.
hence Speed is 226kts.
Im not sure abt the trk. it should be 090 degs, but u since its 085, it must be a hdg correcting for 5 deg right drift.
