SUMMARY
In the discussion, the problem involves calculating the relative speed of object C moving towards A at 0.5c with respect to object B moving towards A at 0.4c. The solution utilizes the relativistic velocity addition formula: U = (U' + V) / (1 + VU'/c²). The calculated result indicates that C is moving towards B at a speed of c/8. The ambiguity regarding the direction of B and C relative to each other is acknowledged but does not affect the calculation of their relative speed towards A.
