let x be the original speed of the crew
\n" ); document.write( "let c be the speed of the current
\n" ); document.write( "speed = distance/time
\n" ); document.write( "with hte current : speed = x +c
\n" ); document.write( "x+c = 11/2
\n" ); document.write( "with speed against current :
\n" ); document.write( "speed = x-c
\n" ); document.write( "x-c = 5/2
\n" ); document.write( "sove the two equations:
\n" ); document.write( "x = 4
\n" ); document.write( "c = 3/2 = 1.5 mph\r
\n" ); document.write( "\n" ); document.write( "
