Default Speed gedanken time.. (time dilation problems 099)

Lets suppose we have a flat surface that is
as far as we know infinite in length and width.

We mark a line and call it the 0 point.
we then mark lines that are 1 mile away from
this 0 point so we will have parallel lines every 1 mile.

An observer stays at the 0 point (A)
an second observer is in a spaceship (B)
traveling at at .5c and the clock that is
at the 0 point(A) starts when it (B) passes the 0 point.
According to basic math, the object will pass by
the 93,000th line in 1/2 second.
and the 186,000th line in 1 second..
(silly basic math)

so...
What time does (B) pass the line according to
the time dilation of (B) while in motion?

If you want to do a real problem, forget the infinite
Newtonian space and time ****, space****. Learn some
relativity.

How Do You Add Velocities in Special Relativity?

Sam is real afraid to answer such a question.
so instead he sticks his head in the sand of relativity.
and expects me to join him..
Sam the osterich..

In return, I ask that you commit seppuku or something that garners a
similar result. When you have completed this task, I will help you
learn.

Yet another simply afraid to give the answer and pleading

I would give you the answer if I obtained something in return. I don't
get that warm fuzzy "helping people learn" feeling when I am explaining
something to you, so I want something tangible. I think ritual suicide,
or an honest attempt at, would be an adequate compensation.

The spacecraft will pass by 161080.7 lines per second.
(93000 * sqrt(1+.5) / sqrt(1-.5) )

Measured how? According to what frame of reference?
