question: After two meteoroids collide at point A, one starts travelling in the direction of point B, while the other starts travelling in the direction of point C, with an angle of 53^\circ  between the two directions. The meteoroid projected in the direction of B is moving at a speed of 7860 km/h, while the other is moving at a speed of 10170 km/h.
  
  
  What distance will the meteoroid travelling towards point B have covered after 29 minutes?
query_wo: Please directly answer the question and provide the final value, e.g., 1, 2.5, 300.
