\n" ); document.write( "In the Mississippi River near New Orleans, the Creole Queen paddleboat travels 6 miles upstream (against the current) in the same amount of time it travels 12 miles downstream (with the current). If the current of the river is 3 miles per hour, determine the speed of the Creole Queen in still water.\r

D=RT OR T=D/R
\n" ); document.write( "T=6/(R-3)
\n" ); document.write( "T=12/(R+3)
\n" ); document.write( "6/(R-3)=12/(R+3)
\n" ); document.write( "12(R-3)=6(R+3)
\n" ); document.write( "12R-36=6R+18
\n" ); document.write( "12R-6R=18+36
\n" ); document.write( "6R=54
\n" ); document.write( "R=54/6
\n" ); document.write( "R=9 MPH. IS THE SPEED OF THE BOAT IN STILL WATER.
\n" ); document.write( "PROOF:
\n" ); document.write( "6/(9-3)=12/(9+3)
\n" ); document.write( "6/6=12/12
\n" ); document.write( "1=1
\n" ); document.write( "
