Two space ships, Ship A and ship B are traveling side by side
at the same speed to the same destination.
Ship A accelerates to half the speed of light for six months
while ship B remains at their original speed.
Now ship A decelerates to a speed that will allow both ships
to arrive at the destination together.
When they arrive at the destination together and check their clocks,
which clock ran slower the ship A clock or the ship B clock?
At the moment ship A starts to decelerate is ship B traveling
faster than Ship A, Ship B is gaining on ship A at that moment?
