Given that : A is 55N 00 E/W
B is 54N 10 E
If the great circle track from A to B is 100 (T), What is the true Rhumb line Track at A
a. 096
b. 107
c. 104
d. 100
first find out the conversion angle (CA)
CA=.5dlongSin(mean lat)
in this case dlong=10
mean lat= .5(54deg 10 +55)=54deg35
CA= .5 x 10 x sin(54deg35)=4.07
Now since it is mentioned northern hemisphere, the GC will lie north of the RL
therefore RL=104
