Two spaceships, A and B, fly by a space station. An observer on
the space station uses a telescope to measure the length of a
meterstick in ship A and finds that it is 0.90 m . He does the same
for ship B and finds that it is 0.60 m . What is the ratio of the
speeds of the two ships relative to the space station, uBuA ?
