\n" ); document.write( "Upstream DATA::
\n" ); document.write( "time = 2 hrs ; distance = x miles ; rate = x/2 mph
\n" ); document.write( "Downstream DATA:
\n" ); document.write( "time = 1 hr ; distance = x miles ; rate = x mph
\n" ); document.write( "----
\n" ); document.write( "Equations:
\n" ); document.write( "b - c = x/2
\n" ); document.write( "b + c = x
\n" ); document.write( "----
\n" ); document.write( "2b = (3/2)x
\n" ); document.write( "Speed of boat = (3/4)x
\n" ); document.write( "----
\n" ); document.write( "2c = (x/2)
\n" ); document.write( "Speed of current = (1/4)x
\n" ); document.write( "---
\n" ); document.write( "Ans:: Ratio of speed of boat to speed of current is 3:1
