Question 474385
against current x-	3.00	hours					
with current x+		2.00	hours					
								
Distance = same=	24						
Boat speed	=x							
current speed 	=y							
t=d/r								
24/(x-y)=3.00	
3(x-y)=	24.00	
3x-3y=24
x-y=8	....................1	
24/(x+y)=2.00	
2.00(x+y)=	24	
x+y=12	...............2	
add 1 & 2
2x=20
x=10 boat speed in still water
Plug value of x in 1								
x-y=8
10-y=8
y=2 mph current speed
