Spaceship \( A \) travels at \( 0.400 c \) relative to an Earth observer.
According to the same observer, spaceship \( A \) overtakes a slower moving spaceship \( B \) that moves in the same direction. The captain of \( B \) sees \( A \) pass her ship at \( 0.114 \) c. Determine the speed of \( B \) relative to the Earth observer.
(A) \( 0.100 c \)
(B) \( 0.300 c \)
(C) \( 0.214 c \)
(D) \( 0.625 c \)
