Question 474799
Distance = same=		3.3						
Roberto speed	=x							
Jaunita speed	=y							
t=d/r								
3.3	/	(	x	-	y	)=	11.00	
11	(	x	-	y	)	=	3.30	
11	x		-11	y	=	3.3	....................1	
3.3	/	(	x	+	y	)=	1.00	
1.00	(	x	+	y	)	=	3.3	
1.00	x	+	1.00	y	=	3.3	...............2	
Multiply (1) by 	1.00							
Multiply (2) by	11.00							
we get								
11	x	+	-11	y	=	3.3		
11	x	+	11	y	=	36.3		
22	x	=	39.6					
/	22							
x 	=	1.8	mph	Roberto speed				
								
plug value of x in (1)								
11	x		-11	y	=	3.3		
19.8			-11	y	=	3.3		
-11	y	=	3.3	-19.8				
-11	y	=	-16.5					
	y	=	1.5	mph	Jaunita speed
