Algebra.Com's Answer #80937 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! distance=(rate)*(time) ... you need to find the times for the two parts of the trip and use them to find distance\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "let x=\"time upstream\", so 5-x=\"time downstream\" ... 12(x)=18(5-x) \n" ); document.write( " |
