Question 999458
Bus 1	x	mph						
Bus 2	x+	12	km/h					
..								
They are moving towards each other								
								
So add up their speed.								
								
combined speed = x+		1	x	12				
(	2	x	+	12	)			
Time =	5	hours						
Distance =   	1100	miles						
Distance = speed * time								
(	2	x		12	)*	5	=	1100
10.00	x	+	60	=	1100			
10	x	=	1100	+	-60			
10	x	=	1040					
/	10							
x=	104	mph						
Bus 1	=	104	mph					
Bus 2	104	+	12	=	116	km/h
