Car A travels at three times the average speed of car B. Car A started to travel at 12:00 o'clock, car B started to travel at 16:00 o'clock. What is the speed of car B (in Km/h) if the total distance that both cars traveled until 18:00 was 3000 Km?	Select the correct option:
A) 100. B) 25. C) 30. D) 150. E) 50.
Total distance= 150.istance travelled by A +150.istance travelled by car B   150.istance= speed*time   150.istance of A= 3x * 6   150.istance of B= x*2   (3x * 6) + (x*2) = 3000   x= 150 KM/hr   150. is the answer
