(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

relative to A, B is moving towards A at a speed of 0.4c. Farther out C is moving towards A at a speed of 0.5c. all motion is along the x axis

how fast is C moving relative to B?

2. Relevant equations

U = (U' + V) / 1+ VU'/c^2

3. The attempt at a solution

0.4c- 0.5c / 1 - (0.4c * 0.5c) / c^2 = 0.125

C is moving at c/8 towards B
