Algebra.Com's Answer #13327 by Paul(988)![]() ![]() ![]() You can put this solution on YOUR website! First your can simplify 1/4 - 0.25h \n" ); document.write( "Truck's peed = 56mph \n" ); document.write( "Cars' speed = 64mph \n" ); document.write( "After 1/4 hour later with the truck = 56(x+0.25) \n" ); document.write( "In where x is the distance. \n" ); document.write( "Car's distance = 64x \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "56(x+0.25)=64x \n" ); document.write( "56x+14=64x \n" ); document.write( "simplify \n" ); document.write( "8x=14 \n" ); document.write( " \n" ); document.write( "x=1.75\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "hence it will take the truck 1.75hour to cross the car \n" ); document.write( "Paul.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
