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 6000 Km?	Choose the correct choice from the following answers.
A) 10.	B) 25.	C) 300.	D) 38.	E) 50.
Total distance= Distance travelled by A +Distance travelled by car B   Distance= speed*time   Distance of A= 3x * 6   Distance of B= x*2   (3x * 6) + (x*2) = 6000   x= 300 KM/hr   300. is the answer
