\n" ); document.write( "-------------
\n" ); document.write( "downstream DATA:
\n" ); document.write( "dist = 12 mi ; time = 2hr; rate = 12/2 = 6 mph
\n" ); document.write( "---
\n" ); document.write( "upstream DATA:
\n" ); document.write( "dist = 12 mi ; time = 3 hr ; rate = 12/3 = 4 mph
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "Downsteam:: b + c = 6 mph
\n" ); document.write( "Upstream :: b - c = 4 mph
\n" ); document.write( "---
\n" ); document.write( "Add and solve for \"b\"::
\n" ); document.write( "2b = 10
\n" ); document.write( "boat speed = 5 mph
\n" ); document.write( "---
\n" ); document.write( "Solve for \"c\"::
\n" ); document.write( "b + c = 6
\n" ); document.write( "5 + c = 6
\n" ); document.write( "current speed = 1 mph
