Algebra.Com's Answer #414013 by mananth(16946)![]() ![]() You can put this solution on YOUR website! Let B's rate be x \n" ); document.write( "A's rate = 2x\r \n" ); document.write( "\n" ); document.write( "They are waling towards each other. So their combined rate = 2x+x=3x\r \n" ); document.write( "\n" ); document.write( "distance = 37.5 miles\r \n" ); document.write( "\n" ); document.write( "time = 5\r \n" ); document.write( "\n" ); document.write( "speed = distance / time\r \n" ); document.write( "\n" ); document.write( "3x= 37.5/5\r \n" ); document.write( "\n" ); document.write( "multiply equation by 5 \n" ); document.write( "15x= 37.5 \n" ); document.write( "/15 \n" ); document.write( "x= 37.5/15 \n" ); document.write( "x= 2.5 mph\r \n" ); document.write( "\n" ); document.write( "B's walking rate = 2.5 mph \n" ); document.write( "A's walking rate = 2.5*2 = 5 mph\r \n" ); document.write( "\n" ); document.write( "m.ananth@hotmail.ca \n" ); document.write( " |
