Question 921118
the distance traveled by both is same when one catches up with the other.						
Let them meet at distance x						
Train A  	speed=	40	km/h			
Train B  	speed=	60	km/h			
						
Time difference  between the starting of the two=			3.00	hours		
						
Time taken by  	Train A  	=	X  /	40		
Time taken by  	Train B  	=	X  /	60		
						
X  /	40	-	X  /	60	=	3
						
LCD -	90					
Multiply equation by	90			90		
						
2.25	x  	-	1.5	x   	=	270
0.75	x  	=	270			
/	0.75					
x=   	360	km	

			
Train B  	speed=	60	km/h			
Distance =  	360	miles				
Time taken =	360	/	60			
Time taken =	6	hours
