a truck eneters the highway at 60mph. a car enters the highway 9 min. later at 65mph. How long until the car will pass the truck?\r
\n" ); document.write( "\n" ); document.write( "Let T be the time when the car passes the truck.\r
\n" ); document.write( "\n" ); document.write( "Using the fact that distance = rate * time we have:\r
\n" ); document.write( "\n" ); document.write( "The disatance traveled by the truck in the 9 minutes or 9/60 hours before the car starts is :\r
\n" ); document.write( "\n" ); document.write( "60*9/60 = 9 miles.\r
\n" ); document.write( "\n" ); document.write( "The car must travel the 9 miles plus the additional distance the truck travels after the car starts before they meet:\r
\n" ); document.write( "\n" ); document.write( "The distance truck travels before they meet is 9 + 60*T. In that same time T the car will travel 65*T Miles.\r
\n" ); document.write( "\n" ); document.write( "They meet when:\r
\n" ); document.write( "\n" ); document.write( "9 + 60*T = 65*T\r
\n" ); document.write( "\n" ); document.write( "Solve for T . \n" ); document.write( "

\n" );
