1 day at 1 gee means you move .25 AU and have a vector of .5
AU per day (using the real equations rather than the FTFB
"Instant acceleration at the beginning of the turn" mode).
So your merchie jumps in, finds his destination on the other
side of the sun, at 12 AU away, and starts burning.  After a
little less than 5 days, he flips and starts decelerating;
after a total of ten days from start he's maneuvering to
dock.

The equation is d = 0.5 a t^2 where d = distance traveled, a
= acceleration (close enough to 10m/sec^2) and t is the
amount of time spent accelerating.  (I'm assuming constant
linear acceleration here, and ignoring plane changes,
matching velocities and gravitational effects).
