Question 913960
boat   	speed	=x	mph					
current     	speed	=y	mph					
against 	current     	0.5	hours					
with 	current     	  1/ 3	hours					
								
Distance with	current     	14	miles		distance against	current     	14	
t=d/r	against	current     	(x-y)					
14.00	/	(	x	-	y	)=	0.50	
								
0.50	x	-	-0.50	y	=	14.00	....................1	
with	current     	(x+y)						
14.00	/	(	x	+	y	)=	0.33	
0.33	(	x	+	y	)	=	14.00	
0.33	x	+	0.33	y	=	14.00	...............2	
Multiply (1) by	0.33							
Multiply (2) by	0.50							
we get	2.00							
0.17	x	+	-0.17	y	=	4.62		
0.17	x	+	0.17	y	=	7.00		
0.33	x	=	11.62					
/	0.33							
x	=	35.04	mph
