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 1000 Km?  Choose the correct choice:	A) 10.	B) 25.	C) 30.	D) 38	E) 50.
Total distance - 1000KM   Time ratio A:B - 3:1   Speed Ratio A : B - 3 : 1   So distance(speed*time) ratio will be - 3*3 : 1*1 - 9:1   So total distance traveled by B - 100 KM   Time taken by B (18:00-16:00 =2) - 2 hours   Speed of B - 50 KMPH   ANSW50.R:50.
