You can put this solution on YOUR website!
boat speed x km/h
\n" ); document.write( "current speed 3 km/h
\n" ); document.write( "..
\n" ); document.write( "against currentspeed x- 3
\n" ); document.write( "withcurrent x+ 3
\n" ); document.write( "..
\n" ); document.write( "Against current 1.2 hours
\n" ); document.write( "with current x+y 1 hours
\n" ); document.write( "Distance is same. D=r*t
\n" ); document.write( "1.2 ( x - 3 ) = 1 ( x + 3 )
\n" ); document.write( "1.2 x - 3.6 = 1 x + 3
\n" ); document.write( "1.2 x - 1 x = 3.6 + 3
\n" ); document.write( "0.2 x = 6.6
\n" ); document.write( "/ 0.2
\n" ); document.write( "x = 33 km/h
\n" ); document.write( "boat speed = 33 km/h
\n" ); document.write( "you can calculate distance. d=rt \n" ); document.write( "

\n" );
