A boat that goes 12 miles per hour in still water takes as long to go 16 miles upstream as to go 32 miles downstream. Find the velocity of the stream.\r

\n" ); document.write( "

Let stream’s speed, be S
\n" );
document.write( "Then we get: 
\n" );
document.write( "   32(12 – S) = 16(12 + S) ----- Cross-multiplying
\n" );
document.write( "   384 – 32S = 192 + 16S 
\n" );
document.write( "– 32S – 16S = 192 – 384 
\n" );
document.write( "          – 48S = – 192
\n" );
document.write( "S, or stream’s speed = , or  mph      
\n" );
document.write( "You can do the check!!
