Q1) Total distance 3222 nm
Q2) 13.4 days
Q3) Need 100+ gal, carry 220 gal, so YES
Q4) TC 12.3d
Q5) Also time of sun's meridian passage, 12 noon LAT
Q6) Still 12.3d ( calculated 12.25d)
Q7) TC to steer 011.8d, less combined error 11.5 leaves
CC to steer 000.3d
However as accuracy by plotting is only to nearest degree
a CC to steer 000d is more practical. I guess that there must
be a way to calculate these questions by trigometric means.
