Algebra.Com's Answer #293941 by mananth(16946) You can put this solution on YOUR website! speed of Y---- x-----------------------------330 miles \n" ); document.write( " speed of X---- x +14------------------------400 miles \n" ); document.write( " \n" ); document.write( "t=d/r Time is same \n" ); document.write( "330/x=400/(x+14) \n" ); document.write( "Cross multiply \n" ); document.write( "330(x+14 )=400*x \n" ); document.write( "330x+4620=400x \n" ); document.write( "400x-330 x=4620 \n" ); document.write( "70x=4620 \n" ); document.write( "/70 \n" ); document.write( "x=66 speed of Y \n" ); document.write( "80= speed of X \n" ); document.write( " \n" ); document.write( " |
