traveling downstream the boat went 12 mph, upstream it went 2 mph what is the speed of the boat and current
\n" ); document.write( "**
\n" ); document.write( "let x=speed of boat in still water
\n" ); document.write( "let c=speed of current
\n" ); document.write( "net speed of boat downstream=x+c
\n" ); document.write( "net speed of boat upstream=x-c
\n" ); document.write( "..
\n" ); document.write( "x+c=12
\n" ); document.write( "x-c=2
\n" ); document.write( "add
\n" ); document.write( "2x=14
\n" ); document.write( "x=7
\n" ); document.write( "c=x-2=5
\n" ); document.write( "..
