Algebra.Com's Answer #413865 by mananth(16946) You can put this solution on YOUR website! Tory pilots her boat 40 km before docking. Emilio continues for another 2 hr, traveling a total of 100 km before docking. How long did it take Tory to navigate the 40 km?\r \n" ); document.write( "\n" ); document.write( "Let their speeds = x km/h\r \n" ); document.write( "\n" ); document.write( "time taken by tory = 40/x hours to dock\r \n" ); document.write( "\n" ); document.write( "Emilio pilots for another 2 hours = (40/x)+2) hours\r \n" ); document.write( "\n" ); document.write( "Emilio pilots 100 km for (40/x)+2) hours\r \n" ); document.write( "\n" ); document.write( "d/t=r\r \n" ); document.write( "\n" ); document.write( "100/ (40/x) +2) =x\r \n" ); document.write( "\n" ); document.write( "100 = x(40/x) +2)\r \n" ); document.write( "\n" ); document.write( "100= 40+2x\r \n" ); document.write( "\n" ); document.write( "2x= 60 \n" ); document.write( "x= 30 \n" ); document.write( "Tory takes 40 /30 = 4/3 hours for 40 km. \n" ); document.write( " |
