Algebra.Com's Answer #516154 by mananth(16946)![]() ![]() You can put this solution on YOUR website! speed * time = distance\r \n" ); document.write( "\n" ); document.write( "let time taken initially be t1 & speed s1 \n" ); document.write( "and time taken later be t2. and speed s2\r \n" ); document.write( "\n" ); document.write( "s1*t1=s2*t2 ( distance same)\r \n" ); document.write( "\n" ); document.write( "65*8 = 40 * t2\r \n" ); document.write( "\n" ); document.write( "65*8/40 = t2\r \n" ); document.write( "\n" ); document.write( "t=13 hours\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
