Question 458699
Boat speed	=	30	mph										
current speed 	=	x	mph										
wind speed													
speed against	current	30	-	x				
speed with	current	30	+	x									
													
Distance against	wind	14	miles										
Distance with 	wind	16	miles										
													
t=d/r	time against = time with												
14/(30-x	)=16/(30	+x)
14(30+x	)=16(30-x)			
420+14x	=480-16x 					
16x+14x	=60								
30x=60										
/30												
x=2	mph	current speed
