Algebra.Com's Answer #574613 by eternalblaze21(2)![]() ![]() ![]() You can put this solution on YOUR website! B is rate of boat=10 mph \n" ); document.write( "W is rate of river/water=3 mph \n" ); document.write( "(B-W)Tu=D <--equation for traveling upstream \n" ); document.write( "(10-3)Tu=32 \n" ); document.write( "7Tu=32 \n" ); document.write( "Tu=32/7 hrs or 4.6 hrs\r \n" ); document.write( "\n" ); document.write( "Additional notes: \n" ); document.write( "If you were traveling downstream, your equation would look like this: (B+W)Td=D \n" ); document.write( " |
